Godaddy Email Denying

When sending an email from Godaddy, this error occurs on certain from email addresses:
Mailbox name not allowed. The server response was: sorry, your mail was administratively denied. (#5.7.1)

So far I have determined they block:
aol.com
hotmail.com
yahoo.com
live.com
comcast.net (added 3/29/2010)


If you happen to run into any other top level domains that do not work with Godaddy, comment so I can update this list. (because being administratively denied is not as cool as it sounds)

School is starting. I'm not ready. Without a doubt, classes this semester will be interesting. So it's time to get back to the grind.

The date today is pretty snazzy too :D
