There's a set of rules in CVS for testing, which check that the
message-id looks sane given the claimed mailer (from the x-mailer and
user-agent headers).  These do help in this situation (since the
message-id format will only match one of the alleged mail clients).

The USER_AGENT_MUTT score in 2.41 was very high.  In 2.43 it's -1.176,
and it'll probably get closer to 0 if more of these spams reach the
corpora used for setting the scores for 2.50.
