So, I've had it with sendmail. And I'm pretty proficient with it -- my first "real" job was partially devoted to keeping it running for CSU. Exim looks like a pretty good replacement that a lot of people http://smtpsurvey.stillhq.com/smtp-survey.cgi?dashboard=1. I had to remove an 'exec' out of my .forward to spamassassin, and then just removed the .forward as exim knows enough to look for a .procmailrc anyway. To see the queue, do 'exim -bp'; to forcibly flush it, do 'exim -qff'. In sendmail, it was 'mailq' and '/usr/lib/sendmail -oQ/var/spool/mqueue -q -v'
