/etc/mail/mailer.conf
mailer.conf5
Configuration file for mailwrapper(8)
Overview
The file /etc/mail/mailer.conf contains a series of lines of the form
name program [arguments ...]
The first word of each line is the name of a program invoking mailwrapper(8). (For example, on a typical system /usr/sbin/sendmail would be a symbolic link to mailwrapper(8), as would newaliases(1) and mailq(1). Thus, name might be “sendmail” or “newaliases” etc.)
The second word of each line is the name of the program to actually execute when the first name is invoked.
The further arguments, if any, are passed to the program, followed by the arguments mailwrapper(8) was called with.
The file may also contain comment lines, denoted by a ‘#’ mark in the first column of any line.

Examples
This example shows how to set up mailer.conf to invoke the traditional sendmail(8) program:
# Execute the "real" sendmail program located in # /usr/libexec/sendmail/sendmail sendmail /usr/libexec/sendmail/sendmail mailq /usr/libexec/sendmail/sendmail newaliases /usr/libexec/sendmail/sendmail
Using Postfix (from ports) to replace sendmail(8):
# Emulate sendmail using postfix sendmail /usr/local/sbin/sendmail mailq /usr/local/sbin/sendmail newaliases /usr/local/sbin/sendmail
Using Exim (from ports) to replace sendmail(8):
# Emulate sendmail using exim sendmail /usr/local/sbin/exim mailq /usr/local/sbin/exim -bp newaliases /usr/bin/true rmail /usr/local/sbin/exim -i -oee
Using mini_sendmail (from ports) to replace sendmail(8):
# Send outgoing mail to a smart relay using mini_sendmail sendmail /usr/local/bin/mini_sendmail -srelayhost
Using dma(8) to replace sendmail(8):
# Execute dma instead of sendmail sendmail /usr/libexec/dma mailq /usr/libexec/dma newaliases /usr/libexec/dma rmail /usr/libexec/dma
