---enable-pop
- Enable client-side support for pop.
-
---with-editor=EDITOR (DEFAULT is vi)
- specify the full path of the default editor to use. If this
- option is not given, then the configuration process will search
- for the `vi' command and use it as the default. If you wish to
- specify an interface which is compatible with MH, then use the
- nmh command `prompter'. If you specify `prompter', then you don't
- need to give the full pathname.
-
---with-hesiod=PREFIX
- Specify the location of Hesiod.
-
---with-krb4=PREFIX
- Specify the location of Kerberos V4 for KPOP support. You will also need
- to specify the option `--enable-pop'. After running configure, you will
- need to change the POPSERVICE #define in config.h if you want to use KPOP
- exclusively (rather than being able to switch between KPOP and normal
- POP3). See the comments inside config.h for details.
-
---with-mts=MTS (DEFAULT is smtp)
- Specify the mail transport system you want to use. The two
- acceptable options are "smtp" (which is the default), and
- "sendmail".
-
- If you use "smtp", this will enable a direct SMTP (simple
- mail transport protocol) interface in nmh. When sending
- mail, instead of passing the message to the mail transport
- agent, `post' will open a socket connection to the mail
- port on the machine specified in the `mts.conf' file
- (default is localhost), and speak SMTP directly.
-
- If you use "sendmail", then `post' will send messages by
- passing forking a local copy of sendmail. Currently it
- will still speak SMTP with this local copy of sendmail.
-
- If you wish to use a transport agent other than sendmail, you will
- need to use a `sendmail wrapper'.
-
---with-pager=PAGER (DEFAULT is more)
- Specify the default pager (file lister) to use. If this option
- is not given, then the configuration process will search for the
- command `more' and use it as the default.
-
---with-smtpservers='SMTPSERVER1[ SMTPSERVER2...]' (DEFAULT is localhost)
- If this option is not specified, the mts.conf file will contain the line
- "servers: localhost", which may be manually edited later. You may find it
- convenient to specify a value at configure-time, however, so that each time
- nmh is reinstalled, the right value will be there.
-
- See the mh-tailor(5) man page for full documentation of "servers:".
+--with-locking=LOCKTYPE (DEFAULT is dot)
+ Specify the locking mechanism when attempting to "inc" or
+ "msgchk" a local mail spool. Valid options are "dot",
+ "fcntl", "flock", and "lockf". Of the four, dot-locking
+ requires no special kernel or filesystem support, and simply
+ creates a file called "FILE.lock" to indicate that "FILE" is
+ locked.
+
+ In order to be effective, you should contact the site
+ administrator to find out what locking mechanisms other
+ mail delivery and user programs respect. The most common
+ reason not to use dot-locking is if the mail spool directory
+ is not world- or user-writeable, and thus a lock file cannot
+ be created.
