Message Not Delivered: Domain Name Of Email Address Not Valid
The message could not be delivered because the recipient's email provider says that the recipient's email address does not exist or cannot receive email.
Fixes
Check the recipient's domain name in the recipient's email address for misspellings or missing letters. If an error is found, correct it in contacts list or address book for next time.
It is possible that the domain is temporarily inactive. If the spelling looks correct, contact provider and if necessary, contact the recipient another way (e.g., phone or text message).
