FROM registration email

Hi,
This is a common problem but I'm not having much luck.

When somebody registers they get a conformation email. The conformation FROM address is a garbage address from the server instead of a normal domain address like: somename@box555555.bluehost.com

I've made sure the admin's email is set and the email global config email is set to the proper domain email.

thanks.

problem solve.. It turned out none of their emails are on the server. They're google accounts.
