I had similar problems, mostly with spam which was sent
from yahoo. The messages that caused me problems had CR's several in headers
(From: "spammer\r" <spam at spam.com>) and I think that they are the cause
for the "Message contains invalid header" response.

If necessary I can post one of the offending messages.
