Hi!
I try to migrate from dovecot 2.3 to dovecot CE 2.4, but within a docker container. But I always get the following error from Dovecot CE:
Error: auth: mysql(host.docker.internal): Connect failed to database (foobar): TLS/SSL error: self-signed certificate in certificate chain - waiting for 1 seconds before retry
This is how I configured the mysql connection:
mysql host.docker.internal { host = host.docker.internal port = 3306 user = ... password = ... dbname = foobar ssl = no }
So MySQL runs on the host machine directly, not in a container - therefore I'm using "host.docker.internal" as an host. But I don't need SQL encryption, since both MySQL and Dovecot run on the same machine. So why the heck does it look like, Dovecot is trying to connect using SSL?
Best regards, Billie
