Hey, my caberpanel installation was running now 1 week and now i running into mailserver issues, this caberpanel seems for me realy unstable.
[000.413] STARTTLS command works on this server
[000.506] Cannot convert to SSL (reason: SSL connect attempt failed error:14094438:SSL routines:ssl3_read_bytes:tlsv1 alert internal error)
[000.506] Note: This same test with Format set to “Debug” may show more
here is the part of the mail.log

Strange now this error is gone but If i do SSL check on postfix i get Always self signed certificate from example.com, but Mail.xxxxx Domain has a valid SSL certificate and it’s also maped in virtual_ssl.map so why postfix is Not using it?
