Re: To send or not to send 'virus in email' notifications?

Notifications from virus scanners is backscatter, just the same as the backscatter generated by Smurf attacks. The virus scanners are contributory technology in the conduct of a denial of service attack in exactly the same way as having directed broadcasts enabled on your routers was (read RFC 2644 for the details). Please let's stop building technology that aids in the conduct of DoS attacks.
