Steps to reproduce:

I updated thunderbird

Actual results:

After update to 78.14.0 I could send emails using my old mail server as SMTP, but I could not read them from the same server.
thunderbird tries to connect and then issues a connection failed after a while.
If I setup everything for connecting to imap without encription (port 143) and it works.

Expected results:

I should be able to read and send since the option security.tls.version.min is configured to 1

Reading and sending are different servers, so probably different certificates.
There could be 1000 reasons the certificate is invalid or something similar. It's not a general problem.

I use the same server for sending and reading.
It's my server I installed and configured it. I have only created one certificate, so it is the same.
Everything was working find until I did the thunderbird update. And since I'm the only one with the root passwod for that server I can tell you that nothing was changed.
This is probably a very uncommon problem, not many imap with TLS 1 servers are still around but for the moment I cannot update it (I'm working on it) But I believe it is a problem, with the option security.tls.version.min set to 1 it should work and it does not.
