Are you talking about the mailwrapper? ie: /etc/mail/mailer.conf

I run qmail and have this in it:

sendmail /var/qmail/bin/sendmail
send-mail /var/qmail/bin/sendmail
mailq /var/qmail/bin/qmail-qread
newaliases /usr/bin/newaliases
hoststat /var/qmail/bin/qmail-qstat

It's one bit of software that I build by hand so I don't know what the
port gets up to on installation.
