[Spambayes] Spam Detection Adds Custom Header Entry

[Dennis W. Bulgrien]

My e-mail server uses a spam filter for the incoming email accounts.  This
filter adds a string into the header, X-Spam-Score, if it finds spam and adds an
attachment explaining why it considered the email to be spam.  Spambayes
(Outlook plug-in) apparently ignores this [unknown] header entry; or maybe it
isn't even given the opportunity to parse them.  I also don't see Spambayes
clues that score based on the presence of attachments, the name of the
attachments, or its contents.  In the present case, it would be helpful as all
attachment names are identical.  May it be known, however, that with these,
Spambayes is still doing a very good job of catching them.
