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(8) and mailq(8) 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 ‘#’ character in the first column of any line.

FILES
/etc/mailer.conf

EXAMPLES
The following is an example of how to set up mailer.conf for the default smtpd(8) MTA suite .

    # Emulate sendmail using smtpd
    sendmail	/usr/sbin/smtpctl
    send-mail	/usr/sbin/smtpctl
    mailq		/usr/sbin/smtpctl
    makemap 	/usr/sbin/smtpctl
    newaliases	/usr/sbin/smtpctl

This example shows how to invoke the traditional sendmail(8) MTA suite in place of smtpd(8).

    # 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
    makemap 	/usr/libexec/sendmail/makemap
    newaliases	/usr/libexec/sendmail/sendmail
    hoststat	/usr/libexec/sendmail/sendmail
    purgestat	/usr/libexec/sendmail/sendmail

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(8) should go away.
