Here's the issue: over the past several months, I've had occasional random instances where the box in question will have slowed to a crawl, and when I log in, I see literally dozens of qmail-smtpd processes, each eating as much CPU as they can

Hmm, okay.

* Netqmail-1.05 with the validrcptto patch, and the patch that lets me route all mail across a relay (forget the name of the patch; relaying through outbound.mailhop.org, a DynDNS.com service)

...huh? Validrcptto I get, the other one, though... You can relay all mail through an external server by just using smtproutes. Are you saying you need to authenticate to that remote server? (If so, I have had very little luck with that patch; it is *full* of bugs, and I haven't had the time to find them all.)

Are you *sure* you aren't using any other patches? For example, if you're using the SSL patch, this can happen if something goes wrong with the dk512.pem and dh1024.pem files. http://forum.swsoft.com/showthread.php?s=2add0886d6e03c00621b94bf45a80858&threadid=40173

@40000000464db27218ab8764 tcpserver: fatal: unable to bind: address already used

Hmmm, that's no good. It looks like you have some rogue tcpserver instances. Make sure your qmail-smtpd run file (/service/qmail-smtpd/run) is correct (you can post it to the list, if you like).
