MailCatch.com: Free, Temporary, Anonymous and Environment Friendly Mails
MailCatch is an email service that allows you to create temporary disposable mailboxes, in a completly anonymous way. When you are asked for an email by a website and you do not want to give your email address (for fear of spam), you can simply give whatever mailbox name you want on the mailcatch.com domain (like whatever@mailcatch.com). Then you go to the site, type in the mailbox name and check your mail. You can also access mail by going to a specified URL or via RSS
