Silly question, how does Bayes deal with a message that has -no-
Message-ID? Unlike NNTP, SMTP does not require a Message-ID, just
reccomends one.
I see many messages a day that come into our mail server that totally lack
a Message-ID (I use that as a spam-sign and assign a value of 1.5 to it ;).
My sendmail daemon synthesizes a Message-ID before delivery but it isn't
there during the filtering process.
