Can you post the rcpt domain of the message?
rzone.de is the German ISP Strato, but I don't know any domains hosted
there that have relay.rzone.de listed as a MX.
Usually they only have this 10 mailin.rzone.de.


Funny thing is, just two days ago a message from Strato's outbound
relays was blocked on my mailserver because it connected to the second
MX without trying the first one before...
