It's not Declude and Imail that's the problem, it's the extreme number of postmaster messages balling up in your spool that will never be delivered. At least that has been my experience, I'm in the same boat (small isp ~6,000 accounts but 60k - 80k messages per day). I wrote a utility to help control this problem, you can download it at http://spamreview.argolink.net/software, it's called Imail bounce control.
My server (p4 1.8GHz, 512MB RAM), went from 5k-6k messages in queue to 400-500. I am fairly aggressive at killing the messages though. Imagine your server is retrying 500 bounce messages every 30 minutes until max tries is reached, now remember you get 500 more to try every 30 minutes, even with only 6 tries that is 3,000 messages to try every 30 minutes. i.e. 3,000 SMTP sessions that should have never been. The program kill messages by 2 conditions, max attempts, and header match. Max tries is self explanatory, header match looks for a perl regular expression at the beginning of each header line of the original message (always included in Imail postmaster messages).

We are a small ISP and now and then we get hit hard by a spammer mass mailing our users ( which equal ~20,000 ) and we get hit our mail server all but shuts down due to the mass amount of incoming mail and Declude scanning each individual email, etc. Our mail server is a 2u Dell server with 2 pentium 1.13 gHz CPUs and 1 gb of ram.
