Thunderbird will display "Security Error: Domain Name Mismatch" if you make a secure connection to a server and the servers domain does not match the domain name in the SSL or TLS certificate. You should verify what server you are connecting to. However, this most frequently occurs when a email provider changes thier domain name but doesn't buy a certificate for the new domain. Thunderbird will display "Server certificate expired" if the SSL or TLS certificate is expired. In both cases you can can continue after getting rid of the alert.


Thunderbird doesn't provide a way to disable security alerts. However, you can prevent both of these security alerts using the "Remember Mismatched Domains" extension. It adds a “Don’t warn me again about this certificate for this domain" checkbox to the Domain Name Mismatch and Expired Certificate warning windows.
