Default ATT / Yahoo Security Cert Issues

I an having a problem with the security Certificate between the ATT email server name and the Yahoo email server name.

The ATT server on the cert is identified as: ipostoffice.worldnet.att.net:995
the yahoo Server is identified as: pop.att.yahoo.com:955
The difference in the two server names creates a problem with the security cert on thunderbird 3.1.10.

I keep getting a pop up requesting a security cert exception as the site is untrusted.

HELP Please

I'd say use the name on the cert if that's what matches but the names are resolving to different IP addresses.

;; ANSWER SECTION:
ipostoffice.worldnet.att.net. 5400 IN A 204.127.217.20


;; ANSWER SECTION:
pop.att.yahoo.com. 1800 IN CNAME pop-sbc.mail.yahoo.com.
pop-sbc.mail.yahoo.com. 300 IN CNAME pop-sbc.mail.am0.yahoodns.net.
pop-sbc.mail.am0.yahoodns.net. 300 IN A 98.139.213.176


Open a ticket with ATT and let them know about the problem.

Please let us know the fix so that others with the same problem can benefit from the answer.

ATT did a remote assist and found "one" location somewhere on my computer where I had the legacy ATT email server listed instead of the yahoo server, that was creating the problem. Took them 2 hours to find it.
