[BUG] Mail SSL fails every 90day

[Dreamer41]

I cant connect SMTP I get message below

certificate Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

I have issued successfully new SSL for mailserver and mail domains, and restart postfix.
When issue new SSL it show it's successfully issued but the new SSL won't be updated correctly somewhere in the server mail system. When do mail tester it show old certificate even new one is successfully installed.
I have fix this issue now over a year every 90 days by running mail debugger but that can't be a permanent solution.

Below log from mail.

Same on CentOS.

Bug in postfix, file vmail_ssl.map.db not upadated automatically, after get new LE certificate. At this time, I do it manually

@Akrobs Can you elaborate as to why you think this is a postfix bug? I'd love to tackle this.

[Akrobs]

@Lvl4Sword, sorry I described the problem incorrectly. This is not a postfix problem, but a Cyberpanel problem. She doesn't update vmail_ssl.map.db, after the certificate issued. For any domain.

[Lvl4Sword]

@Akrobs Appreciate the update. I've got a little bit of a backlog I'm working on, but this is something I want to take a look at.

Are there any updates on the SSL bug? I just did a fresh install and I can't get certs to work on the version I installed. The hostname cert worked fine, but the sites I created are not issuing SSL.

This continues to happen even with the latest commit
