Hi,

        thanx for the tip, I did that on our test server which has a copied setup
(but of course it's own DNS entries).

I increased the verbosity of logging of the postfix cleanup process and I
think I found something interesting:

If I interpret this correctly than opendkim is getting the whole header
information, including "Sender:" and "Message-Id:" field.

Any ideas?
