more annoying than the virus
I find it even more annoying that those people who've had their domain names harvested from infected computers are being bombarded with emails from ISP's who are blocking the emails and are bouncing failed emails back to us. -> One of our clients is infected and had our domain name harvested for the virus and the virus sent out 100's of emails to people with return addresses at our domain - so now we are getting 100's of bounced emails from isps
Atleast we (responsible hosts) can stop the virus emails with our server-side mail scanners, but these bounced emails are starting to upset me

It's also a tad funny that a virus which disguises itself as a failed email is generating 100's of legit bounced emails
