Yesterday, Oct 6, at 3:20 pm, tbird was unable to download messages from my att server. The error message is "The certificate for inbound.att.net does not come from a trusted source". Nothing that I know of has changed when I look at the account settings.

Do I need to contact Att/Yahoo? If so, how can I describe what to tell them, as I have no knowledge of certificates and how they work (or don't work).

What third party application to you have scanning your email and substituting a self signed certificate for encryption for the legitimate one. Probably Norton. These so called security product vendors ll have instructions on how to make Thunderbird trust their self signed certificates. Personally I just don't scan email.

It appears the problem was that AT&T revoked a certificate and didn't replace it until the next day. Things should be back to normal now.
