I actually use the above technique (which is also described on the
main procmail man page--but difficult to understand there) on one of
my mail servers. However, it doesn't play well with CPX: the main
problem is that the technique will cause sendmail to accept all
incoming mail before funneling it to procmail--even if blocked by a
wildcard "nouser" in virtusertable. Then (when the mail is later
rejected as it checks virtusertable), sendmail has to construct a
bounce e-mail message, which--since it is replying to a spammer
address that doesn't exist--will result in a double bounce sent back
to your postmaster  ... Ugly.

Weldon does offer a solution at
http://technoids.org/procmailfilter.html#Appendix, which involves
using access.db. That works OK unless you also use CPX, which requires
a wildcard "nouser" in virtusertable, and requires that you duplicate
much of virtusertable in access.db (yuck)!

I've probably lost you. To summarize: The technique described above
will definitely accomplish what you want, but it is scary to
implement. (Good luck!)

Oh, BTW, I use mailman on another of my servers (also VPS2), and use
mailman's user-contributed mm-handler mailer (instead of procmail or
mail.local). It is written in perl, so you *might* be able to
integrate procmail into it someway. (The thing I like about using
mm-handler is that you can add mail lists without modifying aliases or
virtusertable--everything is through the web interface.)
