I have been a big fan of Mailinator. Not only it helped me with the annoying sites that beg for registration and then bomb with spam but it was invaluable in the debugging of our system when I needed new email accounts to test functionality on production. \r \ \r \ From the news on their site I knew that, actually, The Mailinator Guy has something else to offer a Java developer - DashO - Obfuscator + optimizer. They say Sun and RSA use it in critical applications. Impressive indeed... that if I was not an open-source developer :-) But then - you never know, do you? heh
