Hi Timo!
Creating the mysql-client.cnf didn't change the behavior, it tries to connect even with this minimal configuration:
/etc/dovecot/dovecot.conf: sql_driver = mysql
mysql host.docker.internal { option_file = /etc/dovecot/mysql-client.cnf }
/etc/dovecot/mysql-client.cnf: [client] ssl-mode=DISABLED
Still gets me an error: TLS/SSL error: self-signed certificate in certificate chain
In the meantime I will try to make it work using SSL. But the last time I tried it somehow conflicted with the "ssl_server_cert_file" and "ssl_server_key_file" which point to the certbot/letsencrypt certificates while MySQL generates self-signed certificates.
Thanks for your help so far!
