Our office uses Thunderbird and has been receiving unusual messages and been unable to work effectively since Friday April 9, 2014.
Whenever trying to send a message we receive a window message that says:
Add Security Exception You are about to override how Thunderbird identifies this site. Legitimate banks, stores, and other public sites will not ask you to do this. Server Location: mail.greatersyracuseworks.org Get Certificate Certificate Status This site attempts to identify itself with invalid information. View Wrong Site Certificate belongs to a different site, which could indicate an identity theft.
When we open the Certificate status window, it indicates that the Validity was issued 4/9/14 (when our problems started)
As of today we can receive messages but not send anything…very annoying. Is this related to the recent Heartbleed bug or is something else going on? What are our options to restore service?
Thanks for any help!

Is Thunderbird mistaken about the certificate listing a host name other than your mail server, or is the error interpreting the certificate correctly?
You can check in two places:
- on the first tab of the certificate viewer, "Common Name"
- on the second tab of the certificate viewer, lower box, Extensions category, look for "Certificate Subject Alt Name" to see whether the certificate covers multiple different host names
By the way, Friday was April 11, 2014. If your computer's calendar shows Friday was April 9th, your Mac may be set to the wrong year. (That would lead to a rash of certificate errors in your browsers, too.)
