Well, I think there should be a warning when bogofilter encounters an 
unknown mime specification.  It's O.K. by me to use a simple message like 
"unknown mime encoding", rather than a message that quotes part of the mail 
contents.

Of course any spammer who uses a bogus specification risks the message 
being unreadable - which is _not_ their goal.
