Get enough SPAM lately? Have you ever gone to a website that asks for your email address for no reason (other than they are going to sell it to the highest bidder so you get spam forever)?
Its no signup, instant anti-spam service. Here is how it works: You are on the web, at a party, or talking to your favorite insurance salesman. Wherever you are, someone (or some webpage) asks for your email. You know if you give it, you're gambling with your privacy. On the other hand, you do want at least one message from that person. The answer is to give them a mailinator address. You don't need to sign-up. You just make it up on the spot. Pick email@example.com or firstname.lastname@example.org - pick anything you want (up to 15 characters before the @ sign).
Later, come to Mailinator and check that account. Its that easy. Mailinator accounts are created when mail arrives for them. No signup, no personal information, and when you're done - you can walk away - an instant solution to one way spammers get your address. Its an anti-spam solution for everyone. The messages are automatically deleted for you after a few hours.
