Just for the records:
The mails in question don't get rejected but rather marked as spam
and then get delivered.

The currently best theory is that megamailservers.eu adds a header
  X-Spam-Flag: YES
if it perceives DKIM problems, and that the local anti-spam software
of the receiver takes this header as reason to alter the subject by
the prefix "*****SPAM*****".

Whether it is a good idea to map DKIM failure to a spam marking header
is another interesting topic.

Have a nice day :)
