Issue mails from amazon are blocked by Spam Filter greylist

[PeterKi]

I have configured greylisting on the Tools & Settings -> Spam Filter page.
This used to work properly with amazon until the end of October but in the past weeks I noticed that mails from amazon don't get through anymore
From the mail logs I see that amazon uses different domains to send mails from, like so
a1-101.smtp-out.eu-west-1.amazonses.com
a1-117.smtp-out.eu-west-1.amazonses.com
a1-119.smtp-out.eu-west-1.amazonses.com
a1-11.smtp-out.eu-west-1.amazonses.com
a1-124.smtp-out.eu-west-1.amazonses.com
a1-129.smtp-out.eu-west-1.amazonses.com
a1-134.smtp-out.eu-west-1.amazonses.com
a1-139.smtp-out.eu-west-1.amazonses.com
...
Thus, if amazon resends a mail (because the greylist mechanism has rejected it in the 1st place) it is likely to be sent from a different server which again triggers the greylist reject.
So messages never get through.
If I do: /usr/local/psa/bin/grey_listing --info-server -status on
I don't see any amazon address on the "White domains patterns list:"

How can I get amazon mail servers back to work?

Sorry, I have selected the wrong forum.
This is a Plesk Obsidian for Linux topic.
Can some admin please move it to that forum?
