Hello, I just tried your debugging technique because I am having the same problem and it came up with this exact error
Warning: mail() [function.mail]: SMTP server response: 504 5.5.2 <you@yourdomain>: Sender address rejected: need fully-qualified address in C:\wamp\www\test\WA_Universal_Email\mail_PHP.php on line 254

bool(false)
The problem is I do not have a clue how to fix it. Secondly I do know why it is registering <you@youdomain> because in the UA panel I have input my email address.
