Amavis is nice for small sites, and dial up users, but not too good for larger sites with heavier traffic.
It's a procmailrc based solution, which essentially means that a single mail that goes to a hundred users, gets scanned a hundred times. It's a pretty big drain on the system. Additionally, .forwards don't work anymore , and lastly, it doesn't scan outgoing mail. There is an "outmail" mailer which you can hack into your sendmail.cf to scan outgoing mail, but it's a horrible, ghasty, messy solution...

PS : I have yet to find a decent mail scanning solution which does in process mail scanning. I hacked mimedefang to scan messages using uvscan, which solved most of the problems, but means you have to use a beta sendmail 8.11 with Milter support. I also sometimes end up with high system loads when mailq's get jammed.
