How Mailinator compresses its email stream by 90%
Mailinator is a great product.  My favorite part about it is how whenever I register for something, the clever form validation software always rejects the mailinator.com email address.  Then I visit mailinator, see their alternate domain name du jour in image form (so bots can't harvest it, hah!), and then that works perfectly.  It makes me giggle with joy every time I do it.<p>It's also nice not receiving ads in the mail every hour of every day just because I wanted to try some new YC-startup's product.
