Messages with no MailScanner headers at all?

[hermit921]

We have seen this since we started using MailScanner a few months
ago.  (MailScanner 4.25, postfix 2.0, RedHat 9).  Always very short message
bodies: either an email address or a similar length string of
characters.  Not reproducible.  No idea how often it happens since I am
sure most people don't notice a missing header.  The logs show that
MailScanner handles the messages, but we don't log spam scores.

Our attitude has been it isn't worth a lot of our time since a few people
reported it as a curiosity rather than people complaining.  As long as they
think it received a really low score, it isn't a problem - by definition.
