I have a small number of clients using Thunderbird within Win10 for email, and since it updated automatically last night to Vers 78.5.0 they can no longer download XTRA mail using the usual settings of Port 995/SSL. One of my affected clients using a privately hosted mail server was able to revert to Port 110/No encryption for now, but XTRA doesn't support this. The following is what I found on the Mozilla forum.

“Thunderbird 78 has stopped out of date use of SSLv3 and TLSv1 If server uses out of date insecure protocol then it's not Thunderbirds fault."

"Mozilla disabled TLS 1.0 and 1.1 in the latest versions of Firefox and Thunderbird. Thunderbird 73b and above. This causes issues with anyone connecting via SSL/TLS/StartTLS to services uses 1.1."

I've tried various settings options without success. Outgoing mail is still fine. Any ideas?

Right....think we've got it sorted haha - well the issue caused by Eset anyway.

Open TB, go to options/privacy & security, manage certificates, find Eset's and delete it.

Close TB.

Open Eset, and disable, save, then re-enable the SSL filtering as per these instructions.

Open TB - you can check, but the certificate should be automatically re-created with a current date

Issue should be resolved.

Excellent. That's fixed the 2x XTRA clients I have. I only had to disable and re-enable SSL filtering in Eset to resolve their ones.
