Have customer whose email domain is hosted on GoDaddy. Pop email works fine on pc. On iPhone email works fine except for 1 domain which it won't send to. mine! He can send to me no problem from his pc. On the iPhone whenever he initiates email to me or tries to responds to 1 of my emails, it goes to his outbox, and he gets the error "Cannot send mail. A copy has been placed in your outbox.The recepient was rejected by the server." Whose server - Godaddy? I don't get it. Need help ASAP as this is sort of embarrassing.
