Issue Bad DNS PTR resource record

CupTea

New Pleskian
Hi. Iam new on this forum and rather unexperinced with plesk. It would be great to find help. I was looking for a solution during the last 3 days. Maybe somebody can advice.

I have some troubles with emails sent to web / gmx and some other mail servers. These mail servers refuse to talk to my smtp server.

My setting:
Plesk Onyx v17.0.17
OS Debian 8.7

main ip (85.25.217.103) used by loft10442.serverprofi24.de and domain2.de
2. IP (217.172.190.207) used by comerca.de

Plesk Mail global settings:
Postfix
Dovecot
send mail over domain IP and domain name in smtp greeting

Mails from domain2.de can be sent and received. It works fine. No error messages.
Mails from comerca.de are refused by the mail servers mentioned above.

The log file output (part)

But: The dns template in plesk contains dmarc and spf records!

DNSWatch > Reverse DNS Lookup für 217.172.190.207
Domain
207.190.172.217.in-addr.arpa. PTR 86400 static-ip-217-172-190-207.inaddr.ip-pool.com.
207.190.172.217.in-addr.arpa. NS 86400 ptr1.intergenia.de.
207.190.172.217.in-addr.arpa. NS 86400 ptr2.intergenia.de.


So my question is:
Is it possible to configure Plesk mail server for different domains on different IP adresses, so that the smtp banner does match?
If yes, can you please advice what to do?

Thank you.
