Hi Bill,
thank you so much for your kind reply.
I've tried the tool on appmaildev.com, thank you for pointing me to this service.
As expected: The SPF and DKIM on the domain which does the forwarding (analyze.email) matches both. (also the PTR and there are no blacklistings). It doesn't mention anything about the DKIM of the original domain (before forwarding)
The case is still that the original DKIM of the domain (not being analyze.email) fails after the forward (and then so does DMARC).
Do you guys have any advice about this case and perhaps a way to find out if and on which way headers or the message body is being altered by the forwarding process?
For your information: it is a simple configured forwarding email account configured within Plesk Onyx.
