Issue Problem with Email server

TELLO0815

Basic Pleskian
Hi all,

i have the following problem on Linux Plesk 18.0.32 (was also happen on 31)..

Some emails stuck in the Mail Queue. I tried to setup the sending modus with domain IP - but not helping.

Also I did repair for the mail, but no errors or stuff to fix.

Any idea where to look?

What is logged to /var/log/maillog when the mail queue is processed and tries to send these mails?

Your server or part of your network is blacklisted at T-Online. You need to ask then to remove it from their blacklist. Simply write to the contact mail address mentioned in the error entry.
