If you really want to check you're mail servers performace do the next with one of them out of production and only for testing:
Take rabid/postal combination. Inject mails to smtpd with postal (in you're postfix add the ip of the sender to client exception list) and do constant mail downloads with rabid :). You enter mail with postal and retrieve it with rabid via POP3. I used this some years ago for benchmarking my qmail/vpopmail/courier/mysql implementation and results were quite fun :) with 100.000K mails in queue and loads of 70 and seeing how when I stopped injecting qmail was delivering very very fast; it was really funny :). I did this because you know... when you have "build" you're own smtpd server with you're patches and so... perhaps in some situations you could get core dumps or other kind of problems like bottlenecks and so... this was the test I did as stress test; and it's the test Postfix Quota Reject 2.0 (and 1.0 in it's day) passed although this time with the code of postal changed for sending several recipients in each mail. Sure it can help you :).
