I set up my mail server with Postfix (MTA) and Dovecot (IMAP, POP3). When I tested my installation with an open source webmail interface everthing has been working well: login with username and password, receive mails (port 993, ssl/tls) and send mails (port 587, starttls). Today I started testing local clients beginning with Thunderbird. Here I get an error message like this: Click Me.
In Dovecot I have already changed
ssl_protocols = !SSLv3 !SSLv2
to
ssl_protocols = TLSv1.2 TLSv1.1 TLSv1 !SSLv3 !SSLv2
Moreover I tried to deactivate the OCSP certificate validation in Thunderbird (Settings > Enhanced > Certificates > Validation)
But the issue keeps existing :( Anyone here to help me please?
