Mail can't verify the identity of "pop.att.yahoo.com"…This certificate was signed by an untrusted issuer. The issuer is DigiCert High Assurance CA-3.
I received this pop up on my desk top. "Mail can't verify the identity of "pop.att.yahoo.com"…It also states "This certificate was signed by an untrusted issuer." The issuer is DigiCert High Assurance CA-3. I couldn't find much on the internet about this. This is a good server for mail. Is this truly the issue, that Google is using SSL attempting to be more secure and this is a result of that?
Thank you
