Verify addresses


Verify addresses

I have a primary ATT email address and I have several non-ATT addresses verified so that I can send mail from them via the ATT SMTP server.


I also have an ATT sub-address which does not have those addresses verified -- it looks as if they do not transfer to sub-addresses.


When I log in with the primary address and open Account Info I see the list of verified addresses but no facility to add, cahnge or delete them. When I login with the subaddress I don't see any verified address, but because there is no option to make changes, I cannot add them.


I received the following message from att, but the link it provides does not exist. It brings me to the home page of att support.


How do I verify addresses?


Dear AT&T Internet Services Member,

We have received questions regarding the following error message which is received by customers when they send e-mail using a non-verified e-mail address:

“Unable to send the message. Please verify the e-mail address in your account properties. The server responded: 553 From: address not verified.”

If you have received this error message, you will continue to receive it for emails sent with a non-verified address until you verify your Yahoo! email address or any other non AT&T email addresses (e.g.,,,, etc.). Verification instructions are available on the AT&T Help site If you have already verified your non AT&T email address and are no longer receiving the 553 error message, please disregard this email.

Thank you for your attention to this matter as we work to improve your Internet service. Our goal continues to be to make you a very satisfied customer. If you are experiencing any issues and would like to speak to a customer support representative, please contact us at 1-877-722-3755.

"Verification instructions are available on the AT&T Help site"


I have tried this several times and these instructions NO LONGER EXIST.  Instead, the generic AT&T Support page is shown.
