.Dt MAILER.CONF 5
|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm mailer.conf
|
||||
.Nd configuration file for
|
||||
.Xr mailwrapper 8 .
|
||||
.Sh DESCRIPTION
|
||||
.Pp
|
||||
The file
|
||||
.Pa /etc/mailer.conf
|
||||
contains a series of pairs. The first member of each pair is the name
|
||||
of a program invoking
|
||||
.Xr mailwrapper 8
|
||||
which is typically a symbolic link to
|
||||
.Pa /usr/sbin/sendmail .
|
||||
(On a typical system,
|
||||
.Xr newaliases 1
|
||||
and
|
||||
.Xr mailq 1
|
||||
would be set up this way.)
|
||||
The second member of each pair is the name of the program to
|
||||
actually execute when the first name is invoked. The file may also
|
||||
contain comments, denoted by a # mark in the first column of any line.
|
||||
.Sh EXAMPLES
|
||||
The following is an example of how to set up an
|
||||
.Nm
|
||||
for traditional sendmail invocation behavior.
|
||||
.Bd -literal
|
||||
# Execute the "real" sendmail program, named /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 the fictitious "newmail" program in
|
||||
place of sendmail.
|
||||
.Bd -literal
|
||||
# Emulate sendmail using postfix
|
||||
sendmail /usr/libexec/postfix/sendmail
|
||||
send-mail /usr/libexec/postfix/sendmail

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.

.Dt MAILWRAPPER 8
|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm mailwrapper
|
||||
.Nd invoke appropriate MTA software based on configuration file
|
||||
.Sh SYNOPSIS
|
||||
Special. See below.
|
||||
.Sh DESCRIPTION
|
||||
At one time, the only Mail Transfer Agent (MTA) software easily available
|
||||
was
|
||||
.Xr sendmail 8 .
|
||||
As a result of this, most Mail User Agents (MUAs) such as
|
||||
.Xr mail 1
|
||||
had the path and calling conventions expected by
|
||||
.Xr sendmail 8
|
||||
compiled in.
|
||||
.Pp
|
||||
Times have changed, however.
|
||||
On a modern
|
||||
.Nx
|
||||
system, the administrator may wish to use one of several
|
||||
available MTAs.
|
||||
.Pp
|
||||
It would be difficult to modify all MUA software typically available
|
||||
on a system, so most of the authors of alternative MTAs have written
|
||||
their front end message submission programs so that they use the same
|
||||
calling conventions as
|
||||
.Xr sendmail 8
|
||||
and may be put into place instead of
|
||||
.Xr sendmail 8
|
||||
in
|
||||
.Pa /usr/sbin/sendmail .
|
||||
.Pp
|
||||
.Xr sendmail 8
|
||||
also typically has aliases named
|
||||
.Xr mailq 1
|
||||
and
|
||||
.Xr newaliases 1
|
||||
linked to it. The program knows to behave differently when its
|
||||
.Va argv[0]
|
||||
is
|
||||
.Dq mailq
|
||||
or
|
||||
.Dq newaliases
|
||||
and behaves appropriately. Typically, replacement MTAs provide similar
|
||||
functionality, either through a program that also switches behavior
|
||||
based on calling name, or through a set of programs that provide
|
||||
similar functionality.
|
||||
.Pp
|
||||
Although having replacement programs that plug replace
|
||||
.Xr sendmail 8
|
||||
helps in installing alternative MTAs, it essentially makes the
|
||||
configuration of the system depend on hard installing new programs in
|
||||
.Pa /usr .
|
||||
This leads to configuration problems for many administrators, since
|
||||
they may wish to install a new MTA without altering the system
|
||||
provided
|
||||
.Pa /usr .
|
||||
(This may be, for example, to avoid having upgrade problems when a new
|
||||
version of the system is installed over the old.)
|
||||
They may also have a shared
|
||||
.Pa /usr
|
||||
among several
|
||||
machines, and may wish to avoid placing implicit configuration
|
||||
information in a read-only
|
||||
.Pa /usr .
|
||||
.Pp
|
||||
The
|
||||
.Nm
|
||||
program is designed to replace
|
||||
.Pa /usr/sbin/sendmail
|
||||
and to invoke an appropriate MTA instead of
|
||||
.Xr sendmail 8
|
||||
based on configuration information placed in
|
||||
.Pa /etc/mailer.conf .
|
||||
This permits the administrator to configure which MTA is to be invoked on
|
||||
the system at run time.
|
||||
.Sh FILES
|
||||
Configuration for
|
||||
.Nm
|
||||
is kept in
|
||||
.Pa /etc/mailer.conf .
|
||||
.Pa /usr/sbin/sendmail
|
||||
is typically set up as a symlink to
|
||||
.Nm
|
||||
which is not usually invoked on its own.
|
||||
.Sh DIAGNOSTICS
|
||||
.Nm
|
||||
will return an error value and print a diagnostic if its configuration
|
||||
file is missing or malformed, or does not contain a mapping for the
|
||||
name under which
|
||||
.Nm
|
||||
was invoked.
