.SH NAME
mh-tailor, mts.conf \- mail transport customization for nmh message handler
.SH SYNOPSIS
.I %etcdir%/mts.conf
.SH DESCRIPTION
The file
.I %etcdir%/mts.conf
defines run-time options for those
.B nmh
programs which interact (in some form) with the message transport system.
At present, these (user) programs are:
.BR ap ,
.BR conflict ,
.BR inc ,
.BR msgchk ,
.BR post ,
.BR rcvdist ,
and
.BR rcvpack .
.PP
Each option should be given on a single line.  Blank lines and lines
which begin with `#' are ignored.  The options available along with
default values and a description of their meanings are listed below:
.PP
.B spost
will send messages by forking a
local copy of
.BR sendmail .
.PP
When a user explicitly specifies a \*(lqFrom:\*(rq header in a draft,
.B nmh
uses it
rather than constructing its own.  However, to discourage email forgery, the
SMTP envelope \*(lqFrom:\*(rq and a \*(lqSender:\*(rq header are set to the user's real address.
.RE
.PP
.BR maildelivery :
%libdir%/maildelivery
.RS 5
The name of the system-wide default
.I maildelivery
file.
See
.BR slocal (1)
for the details.
.SS "File Locking"
A few words on locking:
.B nmh
has several methods for creating locks
on files.  When configuring
.BR nmh ,
you will need to decide on the
locking style and locking directory (if any).  The first controls the
method of locking, the second says where lock files should be created.
.PP
To configure
.B nmh
for kernel locking, use the \*(lq--with-locking=flock\*(rq configure option if
you want to use the
.B flock
system call; use \*(lq--with-locking=lockf\*(rq if
you want to use the
.B lockf
system call; or use \*(lq--with-locking=fcntl\*(rq
if you want to use the
.B fcntl
system call for kernel-level locking.
.PP
Instead of kernel locking, you can configure
.B nmh
to use dot locking by using \*(lq--with-locking=dot\*(rq.  Dot locking
specifies that
a file should be created whose existence means \*(lqlocked\*(rq and
whose non-existence means \*(lqunlocked\*(rq.  The name of this file is
constructed by appending \*(lq.lock\*(rq to the name of the file being
locked.  If
.B LOCKDIR
is not specified, lock files will be created
in the directory where the file being locked resides.  Otherwise, lock
files will be created in the directory specified by
.BR LOCKDIR .
.PP
Prior to installing
.BR nmh ,
you should see how locking is done at
your site, and set the appropriate values.
