Mail servers down? Check your firewall logs. Along with the usual suspects like epmap on port 135 and netbios on 137, you’ll see lots of action on ports 9898 and 5554. That’s dabber and sasser to you and me. That surge on port 25? Thank Bagle and Mydoom.

The new models of these devastating worms are on the loose, and unprotected idiots everywhere are happily opening email attachments so they can share them. Is “idiots” too strong?

Nah. If they were smart enough to use decent content and virus filtering, their problems wouldn’t be hammering your equipment.

For now, the best solution may be to hunker down and let your beautiful equipment do its job.
