Dovecot with MySQL over SSL.
Hello! I'm attempting to get Dovecot working with MySQL user database on another machine. I can connect to the MySQL (5.7.26) instance with SSL enabled: mysql -h db.mrst.ee --ssl-ca=/etc/dovecot/ca.pem --ssl-cert=/etc/dovecot/client-cert.pem --ssl-key=/etc/dovecot/client-key.pem --ssl-cipher=DHE-RSA-AES256-SHA -u vmail -p However if I use the same values in dovecot-sql.conf.ext, I get the following error: Jul 19 00:20:18 turin dovecot: master: Dovecot v2.3.7 (494d20bdc) starting up for imap, lmtp, sieve (core dumps disabled) Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:18 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: protocol version mismatch - waiting for 1 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Jul 19 00:20:19 turin dovecot: auth-worker(82996): Error: mysql(db.mrst.ee): Connect failed to database (vmail): Connections using insecure transport are prohibited while --require_secure_transport=ON. - waiting for 5 seconds before retry Database connection string: connect = host=db.mrst.ee dbname=vmail user=vmail password=stuff \ ssl_ca=/etc/dovecot/ca.pem \ ssl_cert=/etc/dovecot/client-cert.pem \ ssl_key=/etc/dovecot/client-key.pem \ ssl_cipher=DHE-RSA-AES256-SHA If I leave the ssl_cipher unset, I get: Jul 19 00:23:41 turin dovecot: auth-worker(83069): Error: mysql(db.mrst.ee): Connect failed to database (vmail): SSL connection error: Failed to set ciphers to use - waiting for 1 seconds before retry Any ideas?

What's your doveconf -n? I suppose this is coming either when
stopping/reloading, or maybe auth process stops when it's been idling
for 1 minute. Do you use Postfix/Exim (or something else) that
authenticates via Dovecot?

Dovecot Director upgrade from 2.2 to 2.3
Hi, I have a setup with 3 Dovecot Director v2.2.36 and director_consistent_hashing = yes ;-) Now I would like to upgrade to 2.3.7, first only Director and after also Backend. Can works fine a ring of director with mixed 2.2 and 2.3 version? Mi idea is to setup a new Director server with 2.3, stop one server with 2.2 and insert the new 2.3 in the current ring to check if works fine. If all works fine I will replace all Director 2.2 with 2.3 version. Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice
