.Sh NAME
.Nm mailer.conf
.Nd configuration file for
.Xr mailwrapper 8
.Sh DESCRIPTION
The file
.Pa /etc/mail/mailer.conf
contains a series of lines of the form
.Pp
.Ar name
.Ar program
.Op Ar arguments ...
.Pp
The first word of each line is the
.Ar name
of a program invoking
.Xr mailwrapper 8 .
(For example, on a typical system
.Pa /usr/sbin/sendmail
would be a symbolic link to
.Xr mailwrapper 8 ,
as would
.Xr newaliases 1
and
.Xr mailq 1 .
Thus,
.Ar name
might be
.Dq Li sendmail
or
.Dq Li newaliases
etc.)
.Pp
The second word of each line is the name of the
.Ar program
to actually execute when the first name is invoked.
.Pp
The further
.Ar arguments ,
if any, are passed to the
.Ar program ,
followed by the arguments
.Xr mailwrapper 8
was called with.
.Pp
The file may also contain comment lines, denoted by a
.Ql #
mark in the first column of any line.

.Sh EXAMPLES
This example shows how to set up
.Nm
to invoke the traditional
.Xr sendmail 8
program:
.Bd -literal -offset indent
# Execute the "real" sendmail program located in
# /usr/libexec/sendmail/sendmail
sendmail	/usr/libexec/sendmail/sendmail
send-mail	/usr/libexec/sendmail/sendmail
mailq		/usr/libexec/sendmail/sendmail
newaliases	/usr/libexec/sendmail/sendmail
.Ed
.Pp
This example shows how to invoke a sendmail-workalike like
.Nm Postfix
in place of
.Xr sendmail 8 :
.Bd -literal -offset indent
# Emulate sendmail using postfix
sendmail	/usr/local/sbin/sendmail
send-mail	/usr/local/sbin/sendmail
mailq		/usr/local/sbin/sendmail
newaliases	/usr/local/sbin/sendmail
.Ed
.Pp
This example shows
how to invoke
a sendmail-workalike with
.Nm Exim
(from ports)
in place of
.Xr sendmail 8 :
.Bd -literal -offset indent
# Emulate sendmail using exim
sendmail	/usr/local/sbin/exim
send-mail	/usr/local/sbin/exim
mailq		/usr/local/sbin/exim -bp
newaliases	/usr/bin/true
rmail		/usr/local/sbin/exim -i -oee
.Ed
.Pp
This example shows the use of the
.Nm mini_sendmail
package from ports in place of
.Xr sendmail 8 .
Note the use of additional arguments.
.Bd -literal -offset indent
# Send outgoing mail to a smart relay using mini_sendmail
sendmail	/usr/local/bin/mini_sendmail -srelayhost
send-mail	/usr/local/bin/mini_sendmail -srelayhost
.Ed
.Pp
Using
.Xr dma 8
to replace
.Xr sendmail 8 :
.Bd -literal -offset indent
# Execute dma instead of sendmail
sendmail	/usr/libexec/dma
send-mail	/usr/libexec/dma
mailq		/usr/libexec/dma
newaliases	/usr/libexec/dma
rmail		/usr/libexec/dma
.Ed

.Sh BUGS
The entire reason this program exists is a crock.
Instead, a command
for how to submit mail should be standardized, and all the "behave
differently if invoked with a different name" behavior of things like
.Xr mailq 1
should go away.
