config: Error: Conflict in setting ssl_cert found from filter

Hi!

I see this intermittent error with my dovecot setup.

The most puzzling part is that it sometimes works and sometimes rejects connections, spitting out the log I attached in systeport (DNS).

I am binding both ipv4 (TLS+SNI) and ipv6 (dedicated addresses). TLS certificates for corresponding DNS are shared across ipv4 / ipv6.

Thank you, Best regards, Jan
