RE: Rejecting mail at SMTP level

Good point.  I've used Listserv which is great at unsubscribing bounces
as well as preventing mail loops.

Good mailing list software will auto-unsubscribe people only after
several consecutive failures (e.g. SmartList).  This behaviour tolerates
transient errors/malconfigurations/blacklistings/whatever.
Plus if you're relying solely on Razor you're just asking for trouble
(as many people have said many times).
