what state of dkim is c= tag ?, if it contains simple, its not that 
simple since its more strong then relaxed

if thats the case, it could be that 8bitmime is not being disabled 
before dkim signing :(

	I don't know the exact details of the antispam configuration. But I 
have asked and the administrator told me that we are not doing ARC 
tests. He told me that the emails are marked as spam because of dkim 
failures.
