Dovecot was logging: dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=172.16.10.169, lip=192.168.15.24, TLS handshaking: SSL_accept() failed: error:14094412:SSL routines:ssl3_read_bytes:sslv3 alert bad certificate: SSL alert number 42, session=<7W9wZZTqCoKsEAxf> Downgraded to 91.8.0 and started thunderbird with --allow-downgrade allowed it to start, but it would still not connect I turning off auto-connect, restarted TB and clicked "Get Messages". That brings up the certificate exception dialog needed for self-signed certificates. After that 91.8.0 worked. Trying the same thing with 102.2.2 does not work. It seems that 102.2.2 will not work with self signed certificates.
