Jesse,

"Content-Type:" gives a mail reader information on how to process a 
message.  Common values are

Content-Type: text/plain
Content-Type: text/html
Content-Type: application/

etc.

The occurrence of an invalid type _could_ be used to add a meta-token, as 
could many other characteristics of a message.  The next step is for 
somebody to do the coding, test the result, and find whether the change is 
useful or not.  After that, the feature can be added to bogofilter.  At 
present, I'm declining the opportunity to take on the task.
