MAILER.CONF(5)

NAME
mailer.conf - configuration file for mailwrapper(8).

DESCRIPTION

The file /etc/mailer.conf contains a series of pairs. The first member of each pair is the name of a program invoking mailwrapper(8) which is typically a symbolic link to /usr/sbin/sendmail. (On a typical system, newaliases(1) and 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.

EXAMPLES
The following is an example of how to set up an mailer.conf for traditional sendmail invocation behavior.

    # 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

This example shows how to invoke the fictitious "newmail" program in place of sendmail.

    # Execute the "real" sendmail program, named /usr/local/sbin/newmail
    sendmail	/usr/local/sbin/newmail
    mailq		/usr/local/sbin/newmail
    newaliases	/usr/local/sbin/newmail

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 mailq(1) should go away.
