My vote is for postfix. I've used postfix on several machines. In my experience throughput of a well tuned postfix can be more than 8x what I could get with sendmail on the same hardware. Postfix is also much easier than sendmail to configure (not to mention much more secure). Postfx doesn't have all the features that sendmail does, but it has plenty. I've never needed a feature that postfix didn't have.

Either way you go I recomend that you throttle your mail generator so it does not overload the mailserver's incoing queue. In my experience MTA performance (postfix, sendmail, or qmail) starts to suffer when the incoming queue gets too large.
