What exactly is the problem? Did you not get an auto-response? If so, how long did you wait? Sometimes it takes a little longer for some reason. Either wait some more, or send another e-mail. Maybe from a different account.
Guys, I've seen (had it happen) whacky things like this. If it's working for some, and not for others, just wait until the next day and send out your e-mail. Also, get an account at the same 'place' as his.
