Resolved Postfix: Ready to start TLS

[Compi]

Server operating system version

Ubuntu 22.04.1 LTS

Plesk version and microupdate number

18.0.46

Hi,

trying to get an email out via SMTP. It's a standard Plesk installation with Roundcube and Postfix.
I get the following error, when I try to send the mail, something with TLS I guess:



What could be wrong? Thanks for any insights!

So in the meantime, I checked if Outlook and SMTP work - yes it does. So it appears to be some kind of Xenforo problem? This is in the error log:


I created an AAA record for titanium.hostname.com with the IPV6 REDACTED:fc9::1 without the extra ":" at the end of the error message.

Whats wrong?

RESOLVED!
I had to give Xenforo the Serverhostname "titanium.hostname,com" and not the "mail.forum.com"
Did the same thing in Outlook now, the warnings are gone!

Thanks!
