I'm running XP Pro sp3. My favorite laptop (I have five) no longer will send or recieve emails except those sent by Bellsouth to advise me that there is an issue with my email account, all other computers send and recieve as they should.The message could not be sent because the server rejected the sender's e-mail address. The sender's e-mail address was noname@bellsouth.net'. Subject '', Account: 'pop.att.yahoo.com (1)', Server: 'smtp.att.yahoo.com', Protocol: SMTP, Server Response: '553 From address not verified - see http://help.yahoo.com/l/us/yahoo/mail/original/manage/sendfrom-07.html', Port: 465, Secure(SSL): Yes, Server Error: 553, Error Number: 0x800CCC78I have reset and confirmed that my account settings are correct, flashed the bios, tried setting up another account with the same settings. Nothing seems to resolve the problem. Any ideas? 1 person needs an answerI do too
