my vote would be for postfix. I did work on a few solaris sparcs during
spring of this year at large insurance company getting about 3 million
emails per month!
Postfix was setup as gateway and relayed to internal lotus notes
servers. The one thing done to the postfix servers was to put 2 pairs
of mirrored drives - 1 for the mail queues, the other with the log que
and the rest of the OS. This helped to reduce disk contention.
compiled postfix and it ran perfectly. They had trend-micro virus
scanner running as well.
Basically, what really helped out was the UCE controls of postfix. That
was a really big help - the volume of email was not an issue. Postfix
ran it without a sweat - the issue that was resolved (too many mails in
the deferred que - directed at non-existing users) was done so by using
the UCE controls of postfix as well as relay user authentication.
