We're in a similar position to where you were back in April, ready to 
retire our old procmail recipes and looking for something that handles 
signatures instead of name patterns, perhaps possibly additionally 
inspecting web/pop/imap in addition to smtp, and am curious if you found 
a product since your post that suited your needs.  Seems like VirusWall 
and WebShield are the only two players in the commercial space...

It might also be interesting to talk about the ease of integrating such 
a product into existing infrastructure - everyone's setup is different, 
but there's probably a common set of problems (and solutions) that would 
be worth discussing.
