It's an important part of your security policy, but I think you're overstating that. Is it too difficult to write a worm which will spread through RPC DCOM (this is just to stay OT) *AND* mass e-mailing. See that? Mass e-mails ... You can have the best port blocking in the world and still be infected in a second. The solution for this is long term improvement of security, strong security policies *AND* education.
