Evo nadjoh resenje ovdje za novije Thunderbird verzije, izgleda da su podigli neki tls minimum security level:

https://support.mozilla.org/en-US/questions/1300809

If you have been effected by Thunderbird 78 changing the minimum tls security level to TLSv1.2 and the server you get emails downloaded from is not using the most up to date protocol then you not be able to get access to server using original server settings. Suggest you test this by trying a reset of the minimum version which by default is now set to 3.

To test this you can do one of the following: Using original server settings.


  • Menu app icon > Options.
  • Scroll all the way to the bottom and click on 'Config Editor' button.
  • Skip past the warning.
  • In search type: tls.version
  • Look for this line: security.tls.version.min
  • Double click on that line to open edit window
  • set the value to 1
  • click on OK


  • Restart Thunderbird.
