If you follow the above article(s) step by step and it still doesn't work then there is probably something else wrong with your system.

this has been a ongoing problem for WEEKS NOW.
Whether you use Yahoo.att or the Mail.bellsouth servers.
I thought it was ATT dropping all support for the mail.bellsouth.net mail servers so I switch to the yahoo.att.pop/smtp servers and the same thing is happening.
Which tells me it is NOT yahoo. It is ATT.
