Address of "smtp.myserver.de" matches an IP address that exim
recognises as being it's own address, however it does not recognise
the domain on the inbound email "smtp.xxx.de" as being a domain that
it accepts mail for.

I'm guessing the MX record for "smtp.xxx.de" points to "localhost"
or possibly to "smtp.myserver.de"

If it looks legit do a whois lookup on smtp.xxx.de and ask the admin
contact what they're trying to do.

I think a misconfiguration something like that can sometimes evade the
inbound/outbound barrier on some other MTAs if poorly configured.
