after the last upgrade , from 68 to 78 , thunderbird refuses to connect to mail servers. neither POP3 incoming mail seerver : "mail.otenet.gr" nor SMTP outgoing mail server  : "mailgate.otenet.gr" the settings that have worked so far are shown in picture : "Thunderbird_ERROR_01" Using these settings i'm sending an email as is shown in picture : "Thunderbird_ERROR_02" but after updating from 68 to 78 this error is diplayed : "Thunderbird_ERROR_03"

I'm working as IT in Public Sector and I don't like to degrade hundreds of installations to previous version

I would appreciate a quick solution for my situation

thanks in advanced

There are two preferences that may need to be changed to correct the 'peer unsupported' error.

Some users report that a workaround is by toggling the value of the option security.tls.version.min from 3 (or 2) to 1. Would it help?
