Really, this is no different to those emails that purport to be from your bank and which ask you to confirm your log-in details.
HAve any of you ever come across "Mailwasher"?
It's a fantastic free service which allows you to vet your emails as they sit on the server before you actually download them. Then you bounce your spam back as if your email doesn't exist. Over a short period of time it learns who your friends are so that even if you were to receive a million spam if there are only 2 new spammers amongst them it'll take you precisely 1 second to review and with no danger of letting trojan emails onto your computer.
As an added bonus it also tells you the domain name that actually sent you the email rather than a "name" that the spammer wants you to see. Brilliant!
