Get automatically sorted out (Score 5)

The spammers try to filter out invalid addresses, so all you need is a real address that seems to be invalid.

I discovered this by accident: I wanted to track which companies give my email address out, so I created a subdomain with throw-away addresses: "nospam.sig11.net", and gave out unique identifiers for the username. (See my email in the header - it is a valid address - do not remove "nospam".)

But the funny thing is: I never received any spam to these addresses. (And for the other addresses I see about 5-10 spam mails a day rejected by my spam filters...) It seems the address gets sorted out because of the "nospam" part.

So the solution is: Get yourself a valid email address with "nospam" or the like in it - The spammers will do the work for you and exclude you from their lists.
