I was primarily wondering if anybody else has a similar issue? All was working well with OTRS 6.0.15 and a previous version of CentOS 7. Unfortunately I can't roll back the upgrade, and now I'm stuck with a system that can't send out mail.
I'm not certain if it is this configuration or if it has to do with the update.
The log gets filled with errors like this:

I tried the direct IP of the mailserver, DNS name was used previously. The mailserver can be contacted from the host, dns name also resolves correctly. I reinstalled the latest rpm package of OTRS via yum.
If more people have this exact error with the exact combination of OTRS 6 and CentOS 7.6.1810, please let me know.
Also, if you have this exact combination, and it works for you, also let me know. Then I will know it is my setup at fault.
