I'm looking for a (preferably) clean way within ZCS to deny delivery of mail to certain addresses within the domains I administer.

For example, in my personal domain, I use my "main" address as a wildcard for the domain and give individual sites that want an email address something specific to the site. That way, if one of them "loses" my address to a spammer, I can just "shut off" the address.

In my pre-Zimbra sendmail days, I did this using the "access" hash table. However, when I try to enable that in procmail on my ZCS server, it does not seem to have any effect.

Any ideas would be greatly appreciated! (I'm getting sick of getting buried in email to addresses I shut off years ago...)
