I was thinking the same, and got the permission to send the following link to the test, where my
problem occurs:

https://blog.lindenberg.one/EmailSecurityTest


In short its mx06.et.lindenberg.one, which is constantly failing.

That it fails at the beginning, is implied in the test, as it starts offering STARTTLS only, if it
has seen some connections from the same IP in the last time.

To shorten the full test.scenario I am currently only sending mails to
somebody@???

Thanks for any kind of support
