[mmh] / ChangeLog

Sun Feb 20 12:17:15 2000 Ruud de Rooij <ruud@ruud.org>

        * Fix security hole in mhshowsbr.c which allowed untrusted shell
          code to be executed.
        * Released nmh 1.0.3.

Thu Feb 10 10:54:36 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Oops.  %-escapes on mhstore lines in mhn.defaults.sh should not
        be surrounded by single quotes, as a shell is not spawned when
        just saving files, and the filenames will end up with literal
        quotes embedded in them.

Fri Feb 04 12:29:12 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Whoever originally added the -help switch to all the commands
        got too cute and had the option itself print out as "-(help)" in
        the -help output.  I guess the idea was to make reference to the
        fact that clearly you know about the -help option since you're
        currently looking at its output.  I think it's a bad idea to
        overload the meaning of the parentheses, however -- they're
        supposed to indicate what abbreviated prefix of the switch you're
        allowed to specify.  It doesn't make sense to show that you're
        allowed to "abbreviate" the switch to its entire length.

Thu Feb 03 17:52:01 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Applied wesley.craig@umich.edu's KPOP patches.  According to him:

              The following patch fixes a problem with requesting a
              service key for a machine that has multiple 'A' records.  It
              also makes "-kpop" a command line option, for users who
              would like to use both "kpop" and "pop".

          Did no testing of the new features, as I don't have access to a
          KPOP server.

        * Modified inc.man and msgchk.man to document Wesley's new -kpop.

        * Modified INSTALL and config.h.in to reflect the new -kpop feature.

Fri Jan 28 17:39:24 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * All %-escapes in mhn.defaults that actually expand to something
        should be surrounded by single quotes.  Added quotes to the ones
        in mhn.defaults.sh that were missing them.

        * Added check for lynx to write mhshow-show-text/html line in
        mhn.defaults.sh.

Thu Jan 27 12:22:25 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * makedir() had multiple bugs dating back to MH.  It passed an
        octal constant to atoi(), which interpreted it as decimal,
        resulting in directories with no user read or execute permissions,
        making nested directory creation fail.  Also, when creating a
        nested directory, correct permissions were only set on the inner one.

        * A second `make install' would always fail because the check for
        whether mh_profile.5 existed was written incorrectly.
        
Wed Jan 26 02:22:00 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added documentation on both types of masquerading to post's man
        page.

Tue Jan 25 22:58:12 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Doug's portability fix of my setgid inc autodetection had a
        caching bug -- if you re-ran configure, uip/Makefile would be
        corrupted, and installation would bomb out on OSes where inc needs
        to be setgid.

        * Implemented a new kind of email address masquerading.  When a
        user writes a custom "From:" header in a draft, nmh uses it rather
        than generating one.  However, the user's true address is used in
        the SMTP envelope "From:" and is revealed in the "Sender:" header.
        Now, when mmailid is set to non-zero, the envelope "From:" uses
        the address specified in the draft "From:" header, and there is no
        "Sender:" header.  This is useful when sending on behalf of a
        remote POP3 account or when remote mail robots incorrectly use the
        envelope "From:" in preference to the body "From:".  This
        processing has only been implemented for post, not for the
        undocumented spost (which was already missing some "From:"
        processing that post has).

Mon Jan 24 22:26:06 2000 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Got rid of the rest of the gcc -Wall warnings that I didn't have
        time for on 1999-07-15 (and, it would seem, some new ones people
        introduced since then).  The primary ones were the warnings that
        default prototypes were being used for [v]snprintf() and
        str[n]casecmp().  As of right now, there are _no_ compilation
        warnings except on dtimep.c-lexed (at least under AIX 4.1.5 and
        Solaris 2.6).

Sun Jan 2 23:42:18 2000 Ruud de Rooij <ruud@ruud.org>

        * Move mhtest from bindir to libdir.

        * Move sendfiles from libdir to bindir.

        * Updated sendfiles manpage to reflect this change.

        * Added documentation for -build and -file switches to repl and 
          forw manpages (patch from Peter Maydell).

        * Fixed interaction between specifying -cc in profile and -group on 
          command-line.

Tue Nov 1 13:48:10 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Changed the version number from 1.0.3 to 1.0.2+dev.  There was
        not unanimous support for my proposed even/odd release/developer
        version number dichotomy.  1.0.2+dev implies release 1.0.2 plus
        some development.

Fri Oct 29 13:42:51 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Upped the version number to 1.0.3.  If we don't do this, then
        when people report bugs against 1.0.2, we won't know "which" 1.0.2
        they're talking about (since the development source is publically
        available via CVS).  I think the Linux kernel version numbers are
        a good model, so the next time we roll a tarball, it should be
        version 1.0.4 (or higher -- anyhow, an even-numbered version).

Fri Oct 29 06:41:08 1999 Doug Morris <doug@mhost.com>

        * Released nmh-1.0.2.

Tue Oct 26 22:57:00 1999 Doug Morris <doug@mhost.com>
        
        * Added check for whether "libtool" is in fact gnu libtool. If
        it is, it is not used. This is the wrong behavior. If vendor
        XYZ later on decides to create yet another libtool, we'll be
        caught again. This works for now.

        * Minor updates to MACHINES refering to Mac OS X.

Thu Oct 21 20:45:37 1999 Doug Morris <doug@mhost.com>

        * Added check for "libtool" (a ranlib type tool for Mac OS X)
        and modified Makefiles so that nmh will build under Mac OS X.

Sun Oct 17 08:28:56 1999 Ruud de Rooij <ruud@ruud.org>

        * Changed repl defaults to partly revert to MH behaviour,
          "-cc all" is now only implied with -group.

        * The replcomps template includes cc: header again (as in MH).

        * Updated repl man page to reflect these changes.

Sat Oct 16 02:57:47 1999 Doug Morris <doug@mhost.com>

        * Tweaked configure to handle Solaris and SunOS after the BIND
        changes. Both need more cleanup.

Sat Oct 16 00:17:36 1999 Doug Morris <doug@mhost.com>

        * Removed BIND define and replaced it with a check for
        gethostbyname (to determine if the host is DNS aware) and a
        check for sethostent. This appears to be the right thing to
        do, but there is no explanation of the reasoning behind the
        BIND define in the code and it appears to have been used for
        multiple purposes. 

Wed Oct 13 15:53:53 1999 Doug Morris <doug@mhost.com>

        * Updated manpages Makefile to link mh-profile.5 to
        mh_profile.5 after installation. Suggestion from Richard Cohen
        <richard@jubjub.demon.co.uk>.

        * Modified configure.in to check for _IO_write_ptr and libio.h
        to determine whether to define LINUX_STDIO instead of using 
        config.guess.

Mon Oct 4 15:22:46 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Added '-L' to the calls of 'ls' in configure.in -- I have seen
        multiple machines in the past where the mail spool was a symlink
        to a directory on another device with more free space.

Fri Oct 1 22:36:56 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Fixed a portability problem in Doug's fix of a portability
        problem in my MAILGROUP autoconf support ('ls -l' vs. 'ls -lg'). 

Sat Sep 25 18:40:43 1999 Ruud de Rooij <ruud@ruud.org>

        * Added config.sub and config.guess to the list of files to be
        distributed.

        * Fixed bug in sbr/fmt_scan.c where an extra newline would be
        added if a list of addresses was split over several header lines.

        * In mts/smtp/smtp.c, undefine strlen and strcpy if they are
        macros, regardless of platform.

        * Allow q to quit mhshow, and n to skip to next part.  Patch from
        Kimmo Suominen <kim@tac.nyc.ny.us>.

        * Modified mhstore to recognize attachments created by sendfiles
        with x-conversions=gzip.

Mon Sep 13 21:20:10 1999 Doug Morris <doug@mhost.com>

        * added explicit cast to long from time_t for tclock in
        post.c.

        * Commented out #ifdefs for <sys/ioctl.h> in termsbr.c since
        it's needed for ioctl() anyway. This prevents a warning about
        implicit definition of ioctl().

        * Moved guesses performed by AC_CANONICAL_SYSTEM back into the
        "User Configuration" section of config.h (moved @TOP@ in
        acconfig.h) so they're easier to find, should someone actually
        want to mess with them.

Sun Sep 12 15:50:34 1999 Doug Morris <doug@mhost.com>

        * updated Makefile.in so it recognized COMPLETION-TCSH and
        COMPLETION-ZSH (only used in make nmhdist). 

        * added prototype for ruserpas to <h/prototypes.h>. Fixes
        warnings in mhparse.c and mhbuildsbr.c.

        * added include checks for <time.h> and <sys/time.h> to
        prevent warnings in fmt_compile.c, fmt_scan.c, lock_file.c,
        sendsbr.c, mhbuildsbr.c, mhcachesbr.c, picksbr.c, and post.c.

        * added include for <zotnet/mts/mts.h> to ali.c, scan.c, ap.c,
        rcvdist.c, rcvstore.c, rcvtty.c, and spost.c to remove
        warnings about implicit definition of mts_init().

        * added <grps.h> to slocal.c to prevent warnings about
        function initgroups.

        * added <h/signals.h> to prevent warning about missing SIGNAL
        function.

        * added function prototypes to smtp.c, whatnowproc.c,
        mhbuildsbr.c, mhparse.c, mshcmds.c, show.c, whatnow.c, mhl.c
        to fix warnings.

        * explicitly declared mbx_style in mshcmds.c and lused in
        fmtdump.c as type static int instead of just static to
        prevent warnings.
        
        * various code cleanups to prevent ambiguous statements
        (brackets for if/thens and parens for complicated if
        statements).


Sun Sep 12 09:19:27 1999 Doug Morris <doug@mhost.com>

        * commented out _cleanup() in mf.c because it's the only
        location in all of the source code where it exists. It was
        preventing compilation on at least linux.

        * Added check for <db1/ndbm.h> which is the new location where
        linux systems appear to be stuffing this header file.

Thu Sep  9 23:15:49 1999 Doug Morris <doug@mhost.com>

        * fixed varous mkstmep bugs introduced in 1.0.1 by me. Whups!

        * added mh_profile SEGV patch from Richard Cohen
        <richard@jubjub.demon.co.uk> that prevents crashing when
        mh_profile doesn't end in a newline. A similar patch was
        previously sent in by Andrew Bettison <andrewb@zip.com.au>.

        * fixed bug in associated with MAILGROUP #define (group "mail"
        is not universal) -- hard to believe, but true.

Tue Sep 7 16:47:03 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Renamed ZSH.COMPLETION to COMPLETION-ZSH and added COMPLETION-TCSH.

Tue Aug 17 16:06:29 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * Automated #define of MAILGROUP and installation of inc as setgid mail
        when the mail spool directory isn't world-writable.

Thu Jul 15 18:37:07 1999 Dan Harkless <dan-nmh@dilvish.speed.net>

        * slocal -debug used to leave a file in /tmp for each message
        processed.  Very bad for folks with slocal -debug in their .forward!

        * Got rid of a ton of compilation warnings.  Most were "junk"
        warnings due to the use of gcc -Wall (without -Wno-parentheses),
        but a few represented real bugs.  There remain many warnings to be
        tackled that are due to missing function prototypes (e.g. snprintf()).

        * Default rcvdistcomps no longer puts a copy of all outgoing
        messages in outbox.  Added an rcvdistcomps.outbox that does.

Sat Jun  9 12:22:47 1999 Doug Morris <doug@mhost.com>

        * Updated configure to check for mkstemp (available on OpenBSD) and 
        substitute it for mktemp if available. 

Thu May 13 16:40:19 1999  Doug Morris <doug@mhost.com>

        * Added config.sub and config.guess and updated acconfig.h and
        configure.in to automatically detect system type and set the
        proper #defines.

Wed May 12 23:41:33 1999  Dan Winship  <danw@mit.edu>

        * Released nmh-1.0.1.

Fri May  7 17:18:28 1999  Dan Winship  <danw@mit.edu>

        * Fixed flist to properly deal with relative folder names.
        Problem noted by Jerry Peek <jpeek@jpeek.com>.

        * Fixed --with-krb4 to work with original Kerberos 4 libraries as
        well as the Kerberos 5 compat libraries. Based on a patch from
        Assar Westerlund <assar@sics.se>.

        * Added a check in configure.in to test if modf is in libc and
        link with libm if not. This is needed by at least Digital UNIX. 
        Problem pointed out by Kevin Oberman <oberman@es.net>.

        * Fix a bug from the "mhn -show" to "mhshow" renaming that
        made the "list" command in whatnow not work for some users.
        From Ruud de Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Replaced "extern int errno" with "#include <errno.h>" in a
        number of files. Suggested by Stephen Wilson Bailey
        <swb@nconnect.net>.

        * Fixed a problem in how "packf -mbox" translated "Return-Path:"
        lines. From Kimmo Suominen <kim@tac.nyc.ny.us>.

        * Fixed a segmentation fault in inc. Patch originally from Ruud de
        Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Allow display of 8bit encoded messages. From Kimmo Suominen
        <kim@tac.nyc.ny.us>.

        * Fixed repl to not add line breaks in the middle of long
        addresses when building a reply. From Ruud de Rooij
        <r.c.m.derooij@twi.tudelft.nl>.

        * Added -library switch to spost so it can parse user aliases like
        post does. From Ruud de Rooij <r.c.m.derooij@twi.tudelft.nl>.

        * Changed configure.in's check for sigsetjmp to properly deal
        with systems like Linux where it is a macro. From
        <elleron@servtech.com>.

        * Fixed a bug in whatnow that could cause it to sometimes exit
        without prompting the user. Based on a patch by Richard Geiger
        <rmg@netapp.com>.

        * Added code to deal with SIGPIPE in mhl so it doesn't print
        "Broken pipe" if you quit out of the moreproc.

        * Documentation: Added a note to MACHINES about Irix make. Added a
        pointer to the online copy of the MH book in INSTALL. Added
        some additional information to the whatnow and packf man pages,
        suggested by Jerry Peek <jpeek@jpeek.com>.

        * Updated INSTALL, FAQ, etc to not refer to Richard as the
        maintainer or math.gatech.edu as the home any more.

1999-02-06  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-1.0.

        * Merged mbx_open and mbx_Xopen in dropsbr.c.  Fixed
          mbx_open so that the mode of zero length maildrops
          would not be changed.

        * Replaced the substitute version of snprintf() with the
          one from the Apache web server.

        * Changed to default mode for creating new messages to 0600
          (this should have been done a long time ago).

        * Changed "flist" to handle searching for multiple sequences
          for each folder.  Also flist will now correctly split
          Unseen-Sequence if it consists of multiple sequences.

        * Added new switches `-unlink' and `-nounlink' to "refile".

        * Added new switches `-unlink' and `-nounlink' to "rmm".

        * More cleanups of slocal output.  Changed adorn() to
          send to stdout, instead of stderr (to match rest of
          verbose printing).

        * Merged mbx_create() into mbx_open, so that creating and
          opening a nonexistent maildrop is done atomically.  This
          removes a bad race condition.

        * Fixed bug that caused slocal to be unable to save to MMDF
          style drop file.

        * Added new wrapper function usr_folder() to slocal.c to
          handle adding message to folder (currently, it still uses
          usr_pipe() to call rcvstore).

        * seq_list() checks for empty folder before scanning for
          sequence information.

        * num_digits() in flist.c and folder.c now returns correct
          value for 0.  Also added sanity check.

        * folder_delmsgs() now correctly decrements internal message
          count.

        * Don't attempt to read sequence information if folder
          is empty.

        * Split seq_read into seq_public and seq_private.

        * Small change to sigmsg.awk, since newer versions of gawk
          interpret 034 as octal.

        * In flist, don't scan for sequence information in empty folder.

        * Updated mhn.defaults.sh to output profile entries for mhshow,
          mhstore, and mhbuild.

        * Changed configuration parameter "mhn-access-ftp" to
          "nmh-access-ftp".  Updated man pages

        * Moved the code in InitMultipart to reverse the order of the
          parts in a multipart, into its own function "reverse_parts()".

        * Changed code in mhbuildsbr.c to store unencoded content
          in the c_cefile structure when building.

        * Changed code in mhoutsbr.c to look for unencoded content
          in the c_cefile structure when outputing message.

        * Changed configuration parameter "mhn-cache" and
          "mhn-private-cache", to "nmh-cache" and "nmh-private-cache",
          since it is used in mhstore, mhlist, and mhshow.  Updated man pages

        * Change configuration parameter "mhn-storage" to
          "nmh-storage", since it is now used in mhstore, mhlist,
          and mhshow.  Updated man pages

        * Add autoconf support for KPOP (kerberized pop).

        * Add autoconf support for Hesiod.

        * Split routines to output a message given a Content structure
          (output_message, output_content, write7Bit, etc..) to a new
          file "mhoutsbr.c".

        * Split output_content(), into output_content() and build_headers().

        * Changed copy_some_headers() in mhstoresbr.c, to use the linked
          list of header fields, rather than reopening the message.

        * Added free_header() to mhfree.c to free structures containing
          header field information.

        * Changed get_content() to use the linked list of header fields
          when parsing the various MIME headers (Content-XXX).

        * Changed get_content() to store linked list of header field
          values when parsing a content.

        * Changed mhbuild, mhn, mhlist, mhshow, mhstore, to use the
          routines in mhcachesbr.c to handle the content cache.

        * Split various funtions (find_cache, find_cache_aux, find_cache_aux2,
          cache_content) into new file mhcachesbr.c.

        * More calls to sprintf/strcpy (primarily in mhparse.c
          and mhbuildsbr.c) converted to snprintf/strncpy.

        * When a message is displayed with `mhshow', it is now
          removed from the "unseen" sequence.

        * Change the default "showmimeproc" to "mhshow".

        * Split "mhn -show" off into separate command "mhshow".

        * Split "mhn -store" off into separate command "mhstore".

        * Split "mhn -list" off into separate command "mhlist".

        * Add sanity checks to context_find(), context_replace(),
          and context_del(), to abort if context file hasn't been
          read.

        * Add calls to context_read(), to the beginning of all nmh
          commands (instead of being called indirectly by context_find).

        * Changes the "substitute" version of vsnprintf/snprintf for
          operating systems without native versions, to just call the
          native vsprintf(), and ignore the buffer length.   This is
          faster, but less secure than the previous version that used
          temporary files.  This should only be a problem for systems
          which do not have a native snprintf(), and require `inc' to
          be setuid/setgid.

        * Lots more calls to sprintf/strcpy converted to snprintf/strncpy.

        * Changes client() routine to take additional parameter, which is
          the buffer length of the parameter "response".  Then added
          buffer length checks for this parameter.

        * Changed getws() to get_fields(), since that is apparently the
          name of a wide character version of gets() on some archetitures.

        * Lots of sprintf/strcpy calls converted to snprintf/strncpy.

        * Change the code in most of the commands that take multiple
          message names/sequences/ranges on the command, such that
          the msgs array is expanded dynamically.  This removes most
          of the limits on the length of command lines.

        * Add additional parameter to copyip(), to specify the
          maximum number of strings that can be copied (security
          fix).

        * Create new function getarguments(), to massage the argument
          vector before parsing it (add any arguments from your
          profile to the beginning of the argument vector).  This
          also removed the general limit on the number of command line
          arguments.

1998-07-04  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.27.

        * Added a new command "delete", that is available during
          a "whatnow" session.  It is equivalent to "quit -delete".

        * Added another parameter to editfile (in whatnowsbr.c),
          that controls whether editfile should remember the last
          program that was exec'ed.  This way the whatnow command
          "mime", will not be re-executed if "edit" is later given
          with no arguments.

        * Changed whatnowsbr.c, so that whatnow doesn't abort if
          mhbuild returns an error.

        * Added parameter to sendsbr(), so you may specify whether to
          rename the draft file.

        * Pass delay time to splitmsg() as a parameter, rather than
          use a global variable.

        * Moved code to rename draft file after sending message from
          splitmsg and sendaux, to sendsbr.

        * Removed all the code in viamail to split messages and then
          mail them.  Replaced this with the standard sendsbr.c routines.

        * Changed sendsbr(), so that when splitting messages into
          messages of type "message/partial", the header fields that
          are copied are more compliant with RFC-2046.

        * Fixed mhbuild to track temporary files better.  They are
          now correctly removed when mhbuild aborts.

        * Created a new man page for "sendfiles".  The information
          about "mhn -viamail" in the "mhn" man page was moved to
          this new page.

        * Changed the name of the "viamail" shell script to
          "sendfiles".  Modified "sendfiles" to use the new
          viamail program.

        * Moved the functionality for "mhn -viamail" out of mhn,
          and into a separate executable called "viamail".

        * When storing MIME contents to a folder using mhn -store,
          they are now accumulated in a temporary file, and then added
          to the folder using folder_addmsg().

        * Moved code to save content to a folder from store_content
          to new function output_content_folder.

        * Moved code to save content to file from store_content to
          new function output_content_file.

        * Moved code to parse storage format string from store_content
          to new function parse_format_string.

        * Fix copy_some_headers() in mhstoresbr.c, so that the
          correct header fields in the first enclosing message/partial
          will be copied (according to RFC2046), when using mhn -store
          to reassemble messages of type message/partial.

        * Fixed bug to openFTP() in mhparse.c, that caused the
          tmp file to not be removed, when transferring a
          message/external file from ftp.

        * Moved the code in mhparse.c to process -auto switch (scan
          contents for the attribute "name"), to a new function
          "get_storeproc" in mhstoresbr.c.

        * Moved routines to free data structures related to MIME
          content from mhparse.c and mhbuildsbr.c, to new file
          mhfree.c.

        * Moved code to show/display MIME content into new
          file mhshowsbr.c.

        * Moved code to store MIME content from into
          new file mhstoresbr.c

        * Moved code to parse MIME content into new
          file mhparse.c.

        * Moved code to list information about MIME content
          into new file mhlistsbr.c.

        * Move part_ok(), type_ok(), content_error(), flush_errors(),
          and set_endian() to new file mhmisc.c.

        * Start to isolate the code to show, list, and store MIME
          messages.  One side effect is that only one flag (-show,
          -list, or -store) can be used at a time now.

        * mhn -store -auto wasn't storing file in correct directory.

        * Removed a few dead variables from sbr/ruserpass.c

        * move code for creating tmp files, and renaming the
          the composition draft in mhbuild, from build_mime()
          to main().

        * remove left-over code in mhbuild.c, mhbuildsbr.c, for
          the -[no]auto switch (which isn't used in mhbuild).

        * split mhn.c into mhn.c and mhnsbr.c (name later changed
          to mhparse.c).

        * split mhbuild.c into mhbuild.c and mhbuildsbr.c.

1998-05-25  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.26.

        * Added (unlisted) options [no]dashstuffing to send, post,
          and whatnow to determine whether to do RFC934 quoting
          (dashstuffing) for encapsulated BCC messages.  The default
          is still the same (dashstuffing).

        * Changed the undocumented feature "nodashmunging" in forw
          and mhl, into the documented feature "nodashstuffing".  The
          default for forw, is still "dashstuffing" for backward
          compatibility, although I don't believe that bursting
          RFC934 digests is very common anymore.

        * Added an option to define REALLYDUMB in the default config.h.
          But it is not on by default.

        * moved creation of config file mts.conf from zotnet/mts
          to etc.  This simplified the Makefile in zotnet/mts.

        * simplified directory support/general to etc.

        * removed unneeded directory support/bboards.

        * split getusername() into getusername() and getuserinfo().

        * Changed getusr() routine to getusername().

        * Slight cleanup in folder_pack.c on code that records the new
          number of the "cur" message when packing.

1998-05-08  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.25.

        * Change install process, so that hard linking the correct mts
          library to libmts.a, is not necessary.  The final link process
          uses the original name of the library.

        * Fixed bug in flist.c and folder.c, so that symbolic links which
          point to directories, will not decrement the number of directory
          links remaining.

        * Split the function list_content (in mhn.c and mhbuild.c) into
          list_content and list_debug.

        * Don't pack (folder -pack) an empty folder.

        * Exit gracefully in flist.c, if no sequence is specified,
          and no "Unseen-Sequence" is given in nmh profile.

1998-02-27  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.24.

        * Small clarification to the man page for `ali'.

        * Fix bug in inc.c so that if both flags `-file' and `-truncate'
          are given, that order doesn't matter.

        * Fix bug in seq_list.c when realloc'ing for
          large sequence line.

1998-02-23  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.23.

        * Add new section on "Transfer Encodings" to man page for mhbuild.

        * In mhbuild.c, split compose_content into compose_content
          (parse and execute composition string), and scan_content (scan
          content, decided transfer encoding, check for clash with boundary
          string).  I did a good amount of rearranging of this code.

        * Moved definitions for data structures for parsing MIME
          messages from mhn.c and mhbuild.c to a new include
          file h/mhnsbr.h.

        * Small amount of rearranging in sendsbr.c

        * Small changes to MAIL.FILTERING file.

        * Add the file MAIL.FILTERING to nmh distribution.

        * Add line to packf so that if message begins with
          "X-Envelope-From:" field, it is converted to "From ".

        * Fix packf to add "From " line to beginning of message,
          even if Return-Path doesn't exist.

        * Add note to MACHINES file that on Linux, configure
          doesn't find the functions sigsetjmp/siglongjmp.

        * Fix configuration for machines that don't have (or find)
          sigsetjmp/siglongjmp.

1998-02-11  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.22.

        * Add a configure check for sigsetjmp.  Add some conditional
          #define's in h/signals.h in case it's not found.

        * Added additional notes about -auto switch in mhn man page.

        * Added note about MM_CHARSET environment variable to
          mh-profile(5) man page.

        * Fix signal problem in mhn.c (change setjmp/longjmp to
          sigsetjmp/siglongjmp).

1998-02-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.22-pre1.

        * Changed the first line in mhl.format from
          " -- using template mhl.format -- " to a blank line.

        * Added note about automimeproc to mh-profile man page.

        * Reorganize the main entry point for parsing a MIME message
          or file in mhn.  Add new function parse_file() as new main
          entry point for parsing MIME files.

        * Add note to mhn man page, that "mhn -file -" will accept the
          source message on the standard input.

        * Changed a sanity check in folder_realloc that was too strict.

        * -norfc934mode is now the default for mhbuild,
          rather than -rfc934mode.

        * Fix mhbuild, so that Content-Description and RFC-822 comments
          from #forw directive will be correctly included if there is
          only one message.

        * Change mhn to correctly default parts of multipart/digest to
          message/rfc822 (leftover code from rfc934mode was removed).

        * Restore HP specific code to zotnet/tws/lexstring.c.  Apparently
          it is still needed.

1998-02-06  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21.

        * If the file given to mhbuild is "-", then accept the draft on
          standard input, and output the MIME message to standard output.

        * Cleaned up code in mhbuild.c that decides what transfer
          encoding to use.

        * Cleaned up code in mhbuild.c that decides what character set
          to use for text contents.

        * Removed old hpux specific code from zotnet/tws/lexstring.c

1998-02-02  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21-pre2.

        * Added the "decode" variable to mhl.format and mhl.header.

        * Added new variable "decode" to mhlsbr.c to decode text in
          header fields as per RFC-2047.

        * Make sure that when decoding RFC-2047 header fields, that any
          spaces at the ends of the encoded text are not ignored, but the
          spaces between encoded word are.

        * Removed #ifdef's for MIME.  MIME support is always compiled in.

        * scan/inc will now decode both Subject and From lines as
          RFC-2047 encoded header fields.

        * Added new function write_charset_8bit() to sbr.  It returns
          the character set to use for 8bit text in composition draft.
          Changed mhbuild to use this function.

        * Split mhn man page into man pages for mhn and mhbuild.

        * mhn -show will only now only use default method for content
          of type plain, if it is NOT a part of a multipart/alternative.

        * Split mhn -build into mhbuild.  Did some code cleanup.

        * Added support for %(decode) to fmtdump.c.

        * check_charset() now accepts US-ASCII as a subset of any
          ISO-8859-X character set.

        * Changed the default "showproc" to mhl, instead of the
          pager more.

        * When reading file into mhn composition file, only need read
          permissions, not write permissions.

        * Added own version of strcasecmp to distribution, since
          nmh calls it frequently with NULL pointers (ughh).

        * Replaced uleq.c with strcasecmp.  Removed uleq.c from
          distribution.

1998-01-22  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.21-pre1.

        * If a message is missing charset parameter to text/plain, show
          will assume US-ASCII, rather than just calling showmimeproc.

        * Change show.c and mshcmds.c to use check_charset to see if text
          message contains valid character set.

        * Added new scan format file "scan.nomime" to support/general
          that doesn't do any RFC-2047 decoding.

        * Modified all the scan format files in support/general to do
          RFC-2047 decoding of Subject field.

        * Did more work on sbr/fmt_rfc2047.c, so that it will correctly
          ignore whitespace between two valid encoded words, but not
          between an encoded word and normal text.

        * Created new file sbr/check_charset.c.  Moved code from
          fmt_rfc2047.c to check for valid character set to this file.

        * Added format escape %(decode) to decode contents of "str" register
          as a RFC-2047 header field.

        * The command install-mh now recognizes the switches -version
          and -help.

        * Added a new argument to print_help.c to decide whether to
          print profile entries (needed for install-mh to prevent weird
          loops).

        * Changed folder_read.c and folder_realloc.c so that mp->lowoff
          is initialize to max (mp->lowmsg, 1) rather than always 1.

        * Changed macros for sequence/attribute manipulation so that
          message status array doesn't need to always start at 1.

        * Small cleanups in folder_realloc().

1998-01-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20.

        * Added configure option --with-pager=PAGER.

        * Added configure option --with-editor=EDITOR.

        * Changed the default format file for mhl (mhl.format) to
          also ignore (not display) the header fields Content-Type,
          Content-Transfer-Encoding, and Content-ID

        * Fixed core dump in addrsbr.c when using %(proper) format function
          and the To: line was missing.

        * Added the file ZSH.COMPLETION to the distribution.

1998-01-04  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20-pre2.

        * Added new switch -snoop to both `msgchk' and `inc', so you can
          watch the POP transaction.

        * Changed "replgroupcomps" to check for Mail-Followup-To header
          first, and use it if available.

        * Changed "replcomps" to check for Mail-Reply-To header
          first, and use it if available.

1998-01-03  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.20-pre1.

        * Changed seq_list.c to dynamically enlarge the buffer for
          collecting the message ranges in a long sequence line.
          This should remove the last hard limit on the size of a
          sequence line.

        * Changed seq_read.c so that can read long sequence lines.
          It will use multiple calls to m_getfld() when m_getfld()
          returns the state FLDPLUS.

        * Changed brkstring.c to dynamically add more space for pointers
          if necessary.  This is needed when splitting up large sequence
          lines.

        * Did some small cleanups in seq_save.c.

        * Added new switches `-[no]unseen' to rcvstore, to control
          whether new messages are added to Unseen-Sequence.

        * Moved locking routines (zotnet/mts/lock.c) to sbr/lock_file.c

        * Changed the internal UNSEEN flag to SELECT_UNSEEN which is
          more appropriate.  Changed the MHPATH flag to ALLOW_NEW.

        * Changed "replcomps" to not include CC and TO lines so that
          that reply message is only directed at the author of the
          message to which you are replying.

        * Added new switch `-group' to command repl, which causes repl
          to use new forms file "replgroupcomps".  This is intended for
          making group replies.

        * Removed #ifdef for ATHENA.

1997-12-28  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.19.

        * Fix repl,forw so that switch `-form file' will not abort
          as ambiguious (silly mistake on my part).

        * Cleaned up the mhn man page.  Added info about a few escapes
          for the formatting/display strings that were not documented
          (%%, %t).  Moved the BNF grammar for the mime composition file,
          to the end of the man page.

        * Added the options -[no]format to the command repl.  The
          switch `-format' will filter the message to which you are
          replying with the standard message filter "mhl.reply", which
          is now included in the distribution.  The `-noformat' option
          will negate the use of -format or -filter and not include
          the message to which you are replying in the draft.

        * Did some cleaning and reorganization on many of the man
          pages.

        * Added debugging switch `-debug' to mhparam, which displays
          the values of all `procs' (and some other misc configuration
          info) that nmh keeps in global variables.

        * When using `refile -preserve', if a conflict occurs, then use
          the next available number above the message number you wish
          to preserve.

        * In forw.c, split the code for creating MIME style forwarding
          out of copy_draft, and into copy_mime_draft.

        * Move routines in mark.c to print sequences, into new
          file sbr/seq_print.c

        * flist will now update the current folder.

        * Added the switches -[no]fast to flist, to replace
          -[no]total.  The previous switches are still accepted
          but now undocumented.

        * More reorganization in flist of the code for
          traversing folders.

        * The command "flist +foo -all" will now scan the folder
          "foo" and all its 1st level children.

        * Add missing include file <h/mh.h> to sbr/snprintf.c

        * Fix alarm bug in rcvtty, so that when it calls external
          process, the alarm is never longer than 30 minutes.

1997-12-17  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18.

        * Fixed bug in mark, so that "mark -list -seq foo" will
          correctly indicate if "foo" is a private sequence.  I found
          this bug mentioned in Jerry Peek's book.

        * Simplified the code in seq_setcur(), since seq_addmsg() now
          retains the public/private status of sequences.

        * Changed sequence handling so that if the switches -public
          or -nopublic, are not specified for the commands mark, pick,
          or rcvstore, then existing sequences will retain their
          previous public/private status.

        * mhparam now handles the mh-sequences profile entry
          correctly.

        * flist -all will now also check readonly folders (for
          private sequences).

        * Improve the leaf optimization for folder command.
          It will now track the number of directories in a folder,
          and stop stat'ing files once it has hit all the subfolders.

        * Renamed m_getfolder to getfolder.  Changed getfolder to
          take option to determine whether it should get current
          folder, or just default folder (Inbox).  Changed rcvstore,
          inc, and rmf to use the new getfolder.

        * flist now indicates if a sequence is private.

        * Change WUNTRACED to 0, in pidwait.c, so that commands will
          wait for stopped processes.

        * conflict will dynamically allocate space for group names,
          so it can now handle system with more than 100 groups.

1997-12-09  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre4.

        * Check if we have enough message status space, before we
          call folder_realloc() in burst, mhpath, and m_draft().

        * mhn will now correctly identify a formatting string of "-"
          for the option -store, and send content to stdout.

        * Change the way that memory for message status is
          allocated.  It is dynamcially allocated separately from
          the folder/message structure.  This required changing
          folder_read.c, folder_realloc.c, folder_free.c.

        * Removed all the MTR code (experimental code for message
          status allocation).

        * Renamed m_readfolder.c to folder_read.c and simplified
          the code.

        * Renamed m_freefolder.c to folder_free.c.

        * Add function trim() to slocal.c to pretty print
          the debugging output.

        * Changed the name of m_packfolder() to folder_pack().
          Changed the name of m_remsg() to folder_realloc().

Wed Dec  3 23:33:38 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre3.

        * Changed installation to add `flists' which is hard linked
          to `flist'.  This is a equivalent to `flist -all'.

        * For flist, -showzero is on by default.

        * Major changes to flist.  Default is now for flist to search
          current folder.  The switch `-all' is now used to specify
          searching all top level folders.  The new switch `-showzero'
          is used to print out folders that don't contain any messages
          in the given sequence.

        * Split BuildFolderList in flist.c into 2 functions
          (BuildFolderList, BuildFolderListR).  Changed these functions
          so that flist now does better leaf optimization, and will stop
          stat'ing directory entries when it knows it has hit all the
          subdirectories of a given directory.

        * Reorganized code in folder.c, so that all relevant folders
          are scanned first and information recorded.  Then all the
          folder summaries at printed out at one time.

        * Made the options of folder(s) more orthogonal.  Now
          "folder -all -noheader -nototal" will do the right thing.

        * Added `-noall' switch to folder, for completeness.

        * Changed the default mode for creation of new folders
          to 0700 (was 0711).

        * Slightly changed the format for flist.  It now indicates
          if a folder is current.  Also the width of the various
          fields are now calculated at runtime.

        * Changed the format for folder(s).  Folder names
          are now left justified.  The width of the various fields
          are calculated at runtime.

Sun Nov 30 19:14:53 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre2.

        * Add paragraph to man page for install-mh and to INSTALL file
          about checking for global mh.profile.

        * Renamed m_find() to context_find().
          Renamed m_replace() to context_replace().
          Renamed m_delete() to context_del().
          Renamed m_update() to context_save().
          Renamed m_getdefs() to context_read().
          Renamed m_foil() to context_foil().

        * Change rcvstore to use routine folder_addmsg(), instead of
          adding message to folder itself.

        * Changed refile, so that if the switch -preserve is used,
          and a conflict occurs for a particular folder, then folder_addmsg()
          will just use next highest available number for that folder,
          instead of exiting.

        * Make folder_addmsg() more robust.  It will make repeated
          attempts to link file into folder if link returns with
          the error EEXIST.

        * Fix bug, so that that if forking sendmail, HELO will be sent
          unless clientname: option is defined but empty (so now it
          is the same as the direct smtp code).

        * Changed sprintb to snprintb (now we pass the buffer length
          to new routine).  Changed code to use new function.

        * Added snprintf to sbr. Added configure check to build it
          if you don't have a native version (but haven't changed much
          code to use it yet).

Thu Nov 13 18:42:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.18-pre1.

        * Fixed alarm bug in slocal, so that alarm is never
          called with a value larger than 30 mintues.

        * Fixed race condition in rmm and refile, so that
          context is updated before external rmmproc is called.

        * Removed all the OVERHEAD code.

        * Move code to add message to folder from refile.c
          to folder_addmsg.c

Fri Jul 25 19:39:29 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Did some rearranging of the internals of inc.c.

        * Make -inplace the default for anno, forw, dist, and repl.

        * Changed --enable-smtp to --with-mts={smtp,sendmail}

        * Created new directory mts/sendmail for direct sendmail
          interface (although it currently still uses SMTP).

        * Removed all the TMA (trusted mail agent) code

        * Removed all the TTYD (terminal access daemon) code

        * Removed all the MF (uucp filtering) code.

        * Removed all the code for BERK.

        * Removed all the code for stand-alone delivery (MHMTS).

        * Split the file mts/sendmail/smail.c into sendmail.c and
          smtp.c.  Changed the name of the directory to mts/smtp.

        * Changed autoconf to use @sysconfdir@ for location of
          configuration files.

        * Changed #define in mhn.c from FTP to BUILTIN_FTP.

Mon Jul 21 03:22:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.17.

        * MAKEDEFS weren't passed down to recursive makes correctly.

        * slocal.c now checks for UTMP_FILE and _PATH_UTMP instead
          of hard-coding "/etc/utmp".

        * rcvtty.c check for _PATH_UTMP if UTMP_FILE is not
          defined.

        * Remove configure checks for ulong and ushort.  Changed
          code to just use unsigned {short, long}.

        * Change addmsg function in refile.c to return new
          number of refiled message.

        * Added check in get_returnpath for empty unixbuf.

        * Cleanup of sbr/pidstatus to use more POSIX macros
          for return value of wait().

        * Change configure to also check /bin for "more".

Sat Jul 12 00:02:23 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.16.

Mon Jun 23 20:13:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added automimeproc, which should replace automhnproc.

        * multipart messages will no longer abort for messages
          of type 8bit or binary (although we still can't really
          deal with binary messages, yet).

        * Fix double free of c_storage.  From John MacMillan.

        * mhn now treats unknown subtypes of "text" as text/plain.

        * mhn changed so that specifying mhn-show-multipart, or
          mhn-show-multipart/{mixed, alternate, etc...) will override
          the use of the internal method for displaying these types.
          Previously mhn would always use the internal method for subtypes
          mixed, alternate, digest, and parallel (even if an alternate
          method was specified in mhn.defaults).

        * mhn show treats unknown subtypes of multipart, as type
          multipart/mixed (as specified RFC2046).

        * mhn checks for the parameter "name" rather than "x-name".
          From MH-6.8.4 patch.

        * Fix double free of ctinfo in user_content when using
          #forw with single message.  From John MacMillan (and
          MH-6.8.4 patch).

        * Changed -mhnproc switch for show, to -showmimeproc.

        * Changed profile entry "mhnproc" to "showmimeproc".

        * Added "mime" option to "whatnow", which calls the program
          "buildmimeproc" (default is mhn -build) to process MIME
           composition files.

        * Added -build switch to mhn, to process MIME composition
          files.

        * Did some reorganizing of mhn.c.

        * Changed casting in mts/sendmail/smail.c from (char) to
          (signed char) so SMTP reply codes work correctly for machines
          which used unsigned chars by default.

Sat Jun 21 01:21:47 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.15.

        * Added new form "scan.unseen" to distribution.  It marks messages
          which are in any sequence in Unseen-Sequence.

        * Do some rearranging of date/time code in zotnet/tws/dtime.c

        * Fix sign extension bugs in fmt_scan.c.

        * Fix m_atoi.c so that strings ending in non-digit characters
          return 0.

        * Split code in burst.c so that finding delimiters of digested
          messages and bursting a message into multiple messages are
          two separate functions (find_delim and burst).

        * Add workaround fo AC_PATH_PROG in configure.in, so
          that BSD4.4 machines can find sendmail, vi, more.

        * Added "-width" option to rcvtty.

        * Change a few variable names in zotnet/mts/client.c since
          they conflict with defines on AIX.

        * Makefile in zotnet/tws assumes lexing of dtimep.lex was
          unsuccessful if resulting file is less than 500 lines long
          (rather than 10, which was previous value), since AIX
          sed gives mangled file of about 200 lines.

        * Extract code in rcvstore.c to link message into folder,
          and put in own subroutine.

        * Extract code in refile.c to link message into folder,
          and put in own subroutine.

        * Moved code to remove messages from folder into own
          routine "folder_delmsgs" in sbr.  Changed rmm.c and
          refile.c to use new routine.

Fri May 16 06:09:31 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed m_seqok to seq_nameok.

        * Changed m_setunseen, msh, mshcmds, flist, and scan to use
          seq_getnum.

        * Changed m_seqflag to return the number of a sequence rather
          than its bit flag.  Changed its name to seq_getnum and renamed
          file to sbr/seq_getnum.c.

        * Removed function m_seqnew and file sbr/m_seqnew.c since it is
          no longer used.

        * Added zero switch to m_seqadd function to zero out bits before
          adding message to sequence.

        * Renamed function m_setvis to m_setunseen, and renamed
          corresponding file in sbr.

        * Renamed function m_setseq to m_setprev, and renamed corresponding
          file in sbr.

        * Changed mark.c and pick.c to use m_seqaddsel and m_seqdelsel.

        * Added new function m_seqdelsel to m_seqdel.c, which deletes
          all selected messages from a sequence.

        * Added new function m_seqaddsel to m_seqadd.c, which adds all
          selected messages to a sequence.

        * Split sbr/m_seqnew.c into m_seqadd.c, m_seqdel.c, m_seqnew.c,
          and m_seqok.c.

Thu May 15 00:53:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed function pack_folder to m_packfolder, and moved it
          from uip/folder.c into its own file sbr/m_packfolder.c

Wed May 14 23:38:00 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed function m_gmsg to m_readfolder.  Renamed file
          sbr/m_gmsg.c to sbr/m_readfolder.c.

Mon May  5 19:57:11 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Expanded rcvtty man page, and added small patch from
          MH-6.8.4 distribution.

Fri May  2 15:24:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.14.

        * Comment out configure test and code for tgetent to allocate its
          own termcap buffer when passed a NULL argument.

Sat Apr 26 03:46:38 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added new options `-checkmime', `-nocheckmime', and `-mhnproc'
          to show.  Restructured code to handle options to various
          `procs' better.  Deprecated `-noshowproc' option and NOMHNPROC
          environment variable.

        * Added new man page `mh-draft' which documents the
          draft folder facility in nmh.

        * Renamed fmtsbr.h to fmt_scan.h.  Renamed fmtcompile.h
          to fmt_compile.h.

        * split fmtsbr.c into fmt_scan.c and fmt_new.c.  Renamed
          fmtcompile.c to fmt_compile.c, and formataddr.c to
          fmt_addr.c.

        * `send -help' wasn't showing the -(no)mime and -split
          options.

Fri Apr 25 02:50:36 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.13.

        * Changed mhpath so it doesn't abort if a message sequence
          such as "mhpath all" expands to more than 1000 messages.
          Also mhpath now dynamically reallocated space for message
          names (The number of command line arguments is still limited
          to MAXARGS).

        * Did some general restructuring of the code in folder.c
          that checks for folder information, and prints it.

Thu Apr 24 01:04:37 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed `folder' to reallocate space for folder names if
          necessary.  So `folders' can now handle more than 300 folders.

Tue Apr 22 14:01:26 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Change configure to use a compile check to see if the tm struct
          has tm_gmtoff, rather than using egrep.

Mon Apr 21 02:19:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.12.

        * Had set_exists and unset_exists macros backwards.

        * Released nmh-0.11.

Thu Apr 10 02:39:53 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added documentation to mh-profile.man about the various
          `procs' (mhlproc, showproc, lproc, etc...).

        * Replace the bit twiddling for SELECTED, UNSEEN, and
          mp->attrstats with macros.

        * If system doesn't have SIGEMT (like Linux), then use SIGTERM
          in msh.c instead.

        * Change fstat to stat in m_gmsg.c since Linux wants
          to hide dd->dd_fd.

        * Merge Linux patch sent in by Michel Oosterhof (original
          patch from bsa@kf8nh.wariat.org).

        * Document an undocumented MH feature.  mhn -form mhl.null
          will suppress the display of the message header.

        * mhparam will now return "mhparam etcdir".

        * Add catproc to /config/config.c and use that in show.c
          and mshcmds.c, rather than hard coding in /bin/cat.

        * Add mhnproc to the list of `procs' in mh-profile.man.

        * Add configure test for lorder and tsort commands.

        * Commented out the padding in the `msgs` struct in h/mh.h

        * Change m_gmsg.c to allocate elements to the `info' array by
          500 elements at a time (rather than MAXFOLDERS / 5).

        * Add note to man page for mhmail that zero length messages are
          not sent.  Need to use -body "" to send empty messages.

        * zotnet/mts/mts.c : compare character with '\0', not NULL.

        * sbr/getcpy.c : assign '\0' to character, not NULL.

        * add m_fmsg to most programs in uip so that they explicitly free
          folder/message structure when done with folder.

        * uip/slocal.c : cleanup processing of sender.  Make sure it is
          defined even if message is missing "From " line.

Mon Mar 31 03:37:35 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.10.

Sun Mar 30 21:46:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure check for <locale.h>.  Turn on LOCALE support
          by default.

Thu Mar 20 03:21:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Reversed previous decision to retain "From " lines in slocal.
          The "From " line is now removed from all messages.

        * inc now saves the date from the "From " envelope in the
          Delivery-Date header for all messages.

        * sbr/m_getfld.c: Clean up processing of Return-Path and
          Delivery-Date from the "From " envelope.

Mon Mar 17 19:03:36 1997  Richard Coleman  <coleman@math.gatech.edu>

        * client.c: cast iaddr to int before comparing return value
          of inet_addr with NOTOK.

Tue Mar 11 04:38:10 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Grep test for signal names was failing on some OS'es because
          of missing tabs in regex.

Sat Mar  8 01:58:22 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.09.

        * Move config files and format files to *.old before installing.

        * Add configure check for killpg.

        * msh.c: include <termios.h> instead of <termio.h> and
          <sys/ioctl.h>.

        * prompter.c: don't include <sys/ioctl.h> anymore.

Thu Mar  6 04:03:24 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added `-mime' and `-nomime' options to `repl'.
          From MH-6.8.4 diff.

Tue Mar  4 03:10:37 1997  Richard Coleman  <coleman@math.gatech.edu>

        * ruserpass.c : removed conflicting prototypes.

        * rcvtty.c : Fixed rcvtty to obey terminal permissions granted
          by `mesg' command.  Previously only worked on BSD machines.

Mon Mar  3 00:18:59 1997  Richard Coleman  <coleman@math.gatech.edu>

        * rcvtty.c : Changed to use #define UTMP_FILE (if exists) rather
          than hard coded "/etc/utmp".

        * Released nmh-0.08.

        * Changed slocal to lock .maildelivery (or file given by -maildelivery)
          when accessing ndbm/db file for duplicate suppression, instead of
          locking database itself.

Thu Feb 27 05:28:09 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Added slocal action `mmdf' to deliver to a file in mmdf format.

        * Changed the slocal actions `file' and `>' to always deliver in
          mbox (uucp) format rather than be determined by RPATHS config
          option.

        * Changed the slocal action `mbox' to deliver in mbox (uucp) format
          rather than mmdf format.

        * slocal now adds Delivery-Date field to all messages (previously it
          only added it to messages when delivering them to a file). The
          "From " line is now retained on all messages if compiling with
          RPATHS, rather than being discarded.

        * rcvpack no longer adds the Delivery-Date field to messages.

Sun Feb 23 22:03:54 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Removed the script packmbox, since it's functionality has been
          added to packf.

        * Changed packf so that it uses mbox (uucp) format by default
          rather than mmdf format.  Added options -mbox and -mmdf to
          packf so you can choose the preferred format.

        * Changed rcvpack so that it uses mbox (uucp) format by default
          rather than mmdf format.  Added options -mbox and -mmdf to
          rcvpack so you can choose the preferred format.

Tue Feb 18 00:01:05 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed nmh to use dot locking by default (although you
          can still easily change this in config.h).

        * Simplified locking code.  Removed code allowing setting of
          locking type in mts.conf.  Now the locking type and locking
          directory (if any) can only be set at compile time.

Fri Feb 14 02:49:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Prefer getting timezone information from tm->gmtoff rather
          than tzset and external timezone variable.

Thu Feb 13 00:35:45 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Fixed typo in ruserpass.c in the variable toktabs.

        * When ruserpass was added to LIBOBJS, it was missing
          the suffix.

        * Released nmh-0.07.

Tue Feb 11 01:29:47 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add check to configure, so that if ruserpass, or _ruserpass
          is not found, build version of ruserpass in sbr.

        * Added define's to discard.c, m_getfld.c, and scansbr.c so
          the code that manipulates internals of stdio, will build
          on SCO 5.x.

        * Added #define to control whether to compile the simple
          built-in FTP client in mhn.

        * Added configure check for ushort and ulong.  Change code
          to use ushort/ulong rather than u_short/u_long.

        * A couple of small cleanups in locking code.

        * Added configure check for gmtoff element in struct tm.

        * Added configure check for tzset.

Fri Feb  7 03:01:57 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.06.

        * Removed code for machines that don't have socket
          interface (how could they get mail anyway?).

        * Removed code for BSD41 machines.  I don't think there are
          many such machines around anymore.

        * Add configure check for function uname, and prefer it
          over gethostname.  General cleanup of zotnet/mts/mts.c.

        * Change all `lseek' calls to use POSIX symbolic constants
          SEEK_SET, SEEK_CUR, SEEK_END.

Thu Feb  6 01:16:30 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Check lex generated file in zotnet/tws and use
          pre-generated version if necessary.

        * Released nmh-0.05.

        * Change to use reliable signals on all platforms that have
          sigaction.  Change so that interrupted system calls are
          restarted for all signals except SIGALRM.  This fixes alarm
          handling code in smail.c for BSD based systems.

        * Added lorder and tsort commands so that created libs can
          be linked in one pass.

Tue Feb  4 01:33:00 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed pidwait so that while it is waiting for a child,
          it should block signals rather than ignore them.

Mon Feb  3 21:05:30 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add checks to configure for dbm_open and -lndbm.

Thu Jan 30 05:15:42 1997  Richard Coleman  <coleman@math.gatech.edu>

        * folder -pop and folder -push were freeing some memory too
          quickly, which caused the entry popped from the stack to not
          become the current folder.

Wed Jan 29 01:28:02 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.04.

        * Define ospeed and PC in termsbr.c is OS doesn't have
          it.

Sun Jan 26 20:25:10 1997  Richard Coleman  <coleman@math.gatech.edu>

        * editfile will create a symbolic link to the altmsg if it
          can't make a link, on any machine supporting lstat.  Formerly
          this would happen only on BSD42 based machines.

Sat Jan 25 22:54:26 1997  Richard Coleman  <coleman@math.gatech.edu>

        * traverse (in popsbr.c) wasn't calling va_start before using
          variable argument list.  Fixes core dump in inc when using POP.

Fri Jan 24 03:27:59 1997  Richard Coleman  <coleman@math.gatech.edu>

        * The variable pass in remotemail needed to be set to
          NULL.  (From MH-6.8.4 diff).  Fixes core dump of msgchk when
          using POP.

        * inc and msgchk were using -rpop by default when configured
          with POP support.  Default is now -norpop.

Thu Jan 23 02:01:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * By default, post will now give the SMTP HELO command with
          the local hostname.  If you specify a hostname with the
          clientname: option in mts.conf file, post will give the
          HELO command with that name instead.  If the argument to the
          clientname: option is empty, no HELO command is given.
          (From the MH-6.8.4 diff)

Wed Jan 22 01:55:45 1997  Richard Coleman  <coleman@math.gatech.edu>

        * When using `-help' for a command, it will also print its
          profile compents from .mh_profile. (From MH-6.8.4 diff)

        * "slocal -file" will now correctly takes its input from
          a file (currently need to specify full path).

Sun Jan 19 20:37:21 1997  Richard Coleman  <coleman@math.gatech.edu>

        * "slocal -debug" will now issue a warning if a non-blank
          line in the .maildelivery file has less than 5 fields.

Sat Jan 18 02:26:41 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed slocal so that code for duplicate suppression
          (MH config was MSGID) is always built. Added the options
          -[no]suppressdup to slocal to turn this on/off.

Thu Jan 16 00:26:34 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.03.

        * Fixed problem where mark would core dump if no
          .mh_sequence file existed.

        * Fixed problem where slocal would core dump if -debug
          option was given, and certain headers were missing.

        * Added patch to slocal to add `folder' (+) action, which
          is shorthand for piping message to rcvstore.  Updated
          man page.

Wed Jan 15 21:30:17 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Changed flist option -unseen to -[no]all.  Cleaned up
          flist man page.

Fri Jan 10 20:36:33 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Fixed flist.  Changed the profile component `Folder-Order'
          to `Flist-Order.  Added option `-sequence' to flist, so
          you can specify the name of the sequence to search for.

Thu Jan  9 00:20:48 1997  Richard Coleman  <coleman@math.gatech.edu>

        * A few minor portability cleanups.  Changed to use PATH_MAX
          rather than MAXPATHLEN.  Don't assume ospeed variable exists
          in termsbr.c.  Removed some conflicting prototypes.

Wed Jan  8 11:05:02 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure test to check if tgetent will accept NULL
          and allocate its own buffer.  Borrowed from zsh.

        * Changed libpath to etcpath.

Mon Jan  6 04:15:35 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Cleaned up source code and Makefiles, so that if your `make'
          supports the VPATH option, you can build nmh in a different
          directory from where the source code is located.

Fri Jan  3 05:05:18 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Released nmh-0.02.

Wed Jan  1 17:41:52 1997  Richard Coleman  <coleman@math.gatech.edu>

        * Split mhook man page into man pages for rcvdist, rcvpack,
          and rcvtty.

Tue Dec 31 03:07:48 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed code to use strerror, rather than using sys_errlist
          and sys_nerr directly.

Mon Dec 30 02:15:25 1996  Richard Coleman  <coleman@math.gatech.edu>

        * -compat switch from install-mh removed.

        * Changed the default POP port from "pop" to "pop3".

Sat Dec 28 13:25:05 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed mhn_defaults to mhn.defaults.  Changed create_mhn_defaults
          (again) to mhn.defaults.sh.  Changed find_program (again) to
          mhn.find.sh.  mhn.defaults.sh now takes the search path
          as an argument.  Default search path is now specified in Makefile
          rather than in script.

Fri Dec 27 16:34:01 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed mtstailor file to mts.conf.  Updated man pages.

        * Changed si_value to si_val in mhn.c, since it conflicts with
          macro defined on Solaris.

Thu Dec 26 02:50:15 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added --enable-nmh-mhe (and --disable-nmh-mhe) to enable/disable
          support for Emacs front-end mhe.  It is on by default.

        * Added the following configure options: --enable-nmh-pop to
          enable client side pop support, --enable-nmh-smtp to enable
          SMTP support.  Client-side pop support now compiles.  Man
          pages for inc, msgchk, mh-chart now correctly added pop
          options if enabled.

Tue Dec 24 14:33:20 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added configure test for bug in C libraries where linker
          can't find ruserpass, but can find _ruserpass.

        * Fixed configure test so that termcap variable ospeed is
          correctly found.

Mon Dec 23 19:40:17 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Source files converted to ANSI C.
        
        * md5 now compiled separately rather than being included
          in mhn.c.  Changed md5 to use memset and memcpy.

Fri Dec 20 02:29:37 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Collected the error routines adios, advise, admonish, and advertise
          into one file (error.c), and did some rearranging of the code.

Thu Dec 19 19:05:29 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added awk script sigmsg.awk (originally written by
          Geoff Wing <mason@werple.apana.org.au> for zsh) to
          automatically generate signal messages for pidstatus.c.
          Added files sbr/signals.c, h/signals.h.  Code now uses
          sigprocmask to block signals (if available).  Code now uses
          signal blocking on non-BSD machines.

Wed Dec 18 01:55:17 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Add configure check for ATTVIBUG.  From Soren's mh autoconf work.

        * Released nmh-0.01.

        * Added configure code to check for type of signals functions
          you have (POSIX or BSD style signals).  Added function
          SIGPROCMASK to simulate sigprocmask on machines that don't
          have POSIX signals.

Fri Dec 13 19:40:48 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added -version switch to all commands.  Also added to
          their man pages.

Mon Dec  9 16:36:54 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Renamed uip/trmsbr.c to termsbr.c and changed it to use
          POSIX termios.h style functions if present.

Tue Dec  3 16:18:39 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Changed support/general/bootmhn.sh to output new mhn_defaults
          file to standard output by default (makes it easier for testing).
          Changed name of script to create_mhn_defaults.  Changed bootmhn.findit
          script to find_program.

Sun Dec  1 10:00:00 1996  Richard Coleman  <coleman@math.gatech.edu>

        * Added patch to uip/folder.c from exmh distribution to
          speed up -recurse option.

        * Added flist command from exmh distribution.  It doesn't work
          yet, but it compiles :-)

        * Changed default location for install to
          /usr/local/nmh/{bin,etc,lib,man}.  Split files so that format
          and configuration files go in nmh/etc, and support binaries go
          in nmh/lib.  Of course, all this can now be changed in the top
          level Makefile. 

        * Started with mh-6.8.3 as based and converted to autoconf.
          Rewrote all the Makefiles.  Currently only works with sendmail/smtp.
          Pop support and plenty of other things, are now broken.
