I do have ENABLE_SSL_SNI=n
I copied it to mailcowdockerized/data/assets/ssl/subdomain.mydomain,com because I was searching for a clue why I can’t connect.
I do have single DNS entry for IMAP and SMTP.
It is wildcard ssl so from my understanding it should work for all subdomains.
What is strange from my perspective I can connect to SMTP just fine on port 25 without ssl,
but it throws errors on SSL/TLS port 465. At the same time IMAP connects via SSL/TLS without problems on port 993.
It’s my first time managing email server and this is first major hiccupa after 2 years.
