I was running sendmail on a P-100 which primarily served as a mailing list host. I was sending out about 140,000 pieces of mail a week, and it was slamming the poor P-100. My average queue delay was about 1 hour 40 minutes for mail delivered without bounceback. I am now running postfix, still on the same hardware, my average delay in queue is under 10 minutes and instead of the delivery process being cpu bound, postfix takes less than 10% of the cpu and mail runs i/o bound. Postfix was essentially a drop-in replacement for sendmail, I think I had to change one place where I was invoking sendmail because I used an odd option that postfix's sendmail compatibility interface did not support. On a different system, I have postfix and cyrus well integrated. I am not nearly at your load levels on that system, so I can't provide any guidance. But if I were running 42% of my CPU for mail delivery, I would look to postfix or another mail system as a way of saving most of that. >My mail queue is high and I have about 20 imap seesions at peak. > >Nfs auto mounts to user home dirs.
