Issue Exclude DKIM verification for incoming mail. Plesk solution not working

[LinqLOL]

Server operating system version

RHEL 8.6

Plesk version and microupdate number

18.0.56 Update #1

For one of our customers mails from one sender is rejected, because of an dkim verification message. Google is accepting these mails without problem. This could have multiple reasons so my idea was to skip DKIM verification for certain senders.

I did find a (new) solution at https://support.plesk.com/hc/en-us/...-a-domain-from-DMARC-check-in-Plesk-for-Linux which is exactly what I needed.

But following these steps still makes the mails get rejected:

Oct 23 08:37:54 srv40 dk_check[1157862]: 6414456012A: DKIM verification (d=mail.example.com, 1024-bit key) failed: signature verification failed
Oct 23 08:37:54 srv40 postfix-local[1157861]: 6414456012A: dk_check: stderr: PASS

Am I missing something?
