I have always received emails from best friend at [email protected] until three or four months ago and have been unable to find the cause. He can receive my emails at [email protected] but cannot respond or send new emails to me. His wife, [email protected], at same location, different computer, can both receive and respond to my emails plus send new emails. As is obvious, all three use att.net. Please respond and correct at earliest if possible. James Warren edited email from spambots and public.
