SOCKS with MIMEDefang?  Nope, not gonna work.

I assume you're talking about accessing external POP and/or IMAP 
servers?  I assume so because I can't think of *any* good reason to not 
force outgoing mail through your own SMTP servers -- it's just too easy, 
and should have next to no impact on your users other than a 
configuration change.

Depending on what you want to do, there are several client-side products 
that will do spam and/or virus checking, if you're not looking to get 
too fancy.  Off the top of my head, though, I can't think of any 
anywhere near as thorough and flexible as what you'd get with MIMEDefang.
