What is mailexpire?

For those of you who don't know, mailexpire is a free anti-spam service, operating at www.mailexpire.com.

If you need to fill in a registration form, but would rather not give away your real email address, generate a free mailexpire alias and give them that instead. Any mail sent to your alias will be forwarded to your normal inbox, so you don't have to run around your junk hotmail or gmail accounts to find it. But, when you decide you don't want any more mail from the source, you can kill off the alias and you'll never hear from them again.

You can always see which alias was used to send you mail, so if you start getting spam, you can tell where it came from. You can identify the spammers.
