We currently have a 3 system Mail server set up - two machines are the load balanced frontends running Dovecot and Postfix, and the third machine is our NFS. Over the past 4 months or so, I've tweaked and optimized our mail servers, and we receive roughly 3 million emails a day combined through this setup.

Sometimes, the IO Wait is horrible on the load balanced servers - it can get up into the 80-90% range sometimes - it's usually when a lot of email is being passed, or there are a lot of POP3 and IMAP connections.

I updated http://wiki.dovecot.org/POP3Server. See maildir performance and session locking.
