mailer.conf —
configuration file for
mailwrapper(8)
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.
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
mail(1), mailq(1), newaliases(1), dma(8), mailwrapper(8), sendmail(8)
postfix(1) (ports/mail/postfix), dma(8) (ports/mail/dma), exim(8) (ports/mail/exim), mini_sendmail(8) (ports/mail/mini_sendmail)
mailer.conf appeared in
NetBSD 1.4.

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.
