maybe the AV vendors could suply a 'to mail or not to mail' flag within their databases, based on character of the virus... any of them lurking here? :) -- deejay

Absolutely not.

SoBig.F, like many others, forges the sender address. That means that your notifications: 1) Don't make it back to the person with the infection 2) Simply add more clutter to the mailbox of the person whose address was used (in addition to all the bounce messages)

In the enterprise, this is a great argument for scanning outbound email with positive identification of whose outbound mail you're scanning.

Considering the amount of email traffic generated by responding to forged virus laden email from culprits like sobig should email virus scanning systems be configured to send notifications back to sender or not?
