but few years ago Thunderbird (on CentOS 7) for me refused to connect to
Port 993 or Port 465 if I used a self-signed certificate even though the

possible the domain name you use for the dovecot server is not resolving
because of a dnssec validation failure.

supporting POP around 2001.
Other than 110
