out of office and non-delivery message don t pass trough mailscanner/spamassassin

[Joolee]

Your out of office messages are pretty malformed seeing the rules that it
hits. Best solution, of course, would be to fix the messages themselves.
Most E-mail packages don't give you that option though. Another solution is
to dig in the headers of the messages, find a (few) unique characteristics
and make a (meta) rule with a negative score. This won't solve your problem
on other Spamfilters though.
