configuration file for mailwrapper(8)
The file /etc/mailer.conf
contains a series of pairs.
The first member of each pair is the name of a program invoking
typically a symbolic link to /usr/sbin/sendmail
. (On a
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.
The following is an example of how to set up
for the default smtpd(8)
# Emulate sendmail using smtpd
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
Perry E. Metzger
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
should go away.
