good point, but if using smtp it probably contacts remote smtp servers
directly, not via your internal gateway.  therefore blocking port 25
outbound should be sufficient (and should be SOP anyway).  my internal
gateway does not do any spam/virus checking however i am reconsidering.
it sucks to get blacklisted.
