However, I would like to try setting up multiple sendmail processses with their own configurations.

Haven't tested in production yet, but seems to be working on my laptop. First created a /usr/local/etc/rc.d/sendmail-msa rc script. The main problem seems to be you can't specify an alternate pidfile for each process. So stopping the msa will require hacking sendmail perhaps. Unless someone comes up with a good idea. I'm thinking possibly getting the pid from the maillog. Attached is my rc script. Its not the best, but oh well. In /etc/rc.conf I added the following lines: sendmail_msa_enable="YES" sendmail_msa_flags="-bd -C/etc/mail/sendmail-msa.cf -L sm-msa" <------ /etc/mail/freebsd.mc ------> FEATURE(`no_default_msa')dnl <------ /etc/mail/sendmail-msa.mc ------> dnl Enable for bot IPv4 and IPv6 (optional) FEATURE(`no_default_msa')dnl DAEMON_OPTIONS(`Port=587, Name=MSA, M=Ea')dnl adding the a requires auth dnl DAEMON_OPTIONS(etc, etc dnl DAEMON_OPTIONS(etc, etc I'm sure I'll have to make some more changes, but that should get the ball rolling. Suggestions for improvement are appreciated.
