Check this place out for some serious e-mail action. The Owner of 10 Minute Email states you can claim a temporary e-mail address through his site, which you can use for any number of reasons, not least of all, registering with websites that require validation (when you don’t want to give out your real e-mail address). After the ten minutes expires, so does the temporary e-mail address. Rinse and repeat as many times as you need. Be wary though; they are currently being slashdotted, so as popularity rises with this service, websites may ban the 10minute domain to avoid your anon status.
