that is the normal behavior if you force a auth-mech on the client which the server don't announce - auth-mech and TLS certificicate are completly different worlds just configure thunderbird to use plain instead encrypted auth which means CRAM-MD5 at the end of the day, by default dovecot only offers PLAIN which is fine inside a TLS connection you can only support CRAM-MD5 with passwords stored as plain-text [root@testserver:~]$ doveconf -n | grep -i mech auth_mechanisms = CRAM-MD5 DIGEST-MD5 APOP LOGIN PLAIN [root@testserver:~]$ doveconf -d | grep -i mech auth_mechanisms = plain
