Agreed.  (I thought I covered that in my last email.  Maybe I wasn't clear.)

I'm glad to know that Mailman's "Topic" feature (key word matching) 
works on the subject.  I thought it was looking explicitly for the 
Keywords: header.  That does help some.

Of course, that does rely on posters putting proper keywords in the 
subject.  Which is less than reliable.

I have long wished that Mailman's "Topic" feature would also look for 
keywords in the body in addition to the Subject and Keywords: header.

I feel like Mailman's "Topic" feature is under utilized.  :-/

Oy vey.  I would be afraid of how that would likely not scale.  I also 
see security implications in that.  (Running subscriber specified RegEx 
(code) on a server.)  I also feel like that would be mainly usable for 
the single user that specified the RE.  Or are you proposing that the 
user specified RE show up as available "Topics" that people can choose 
to subscribe to?

I feel like this would be best implemented if the poster added a blob of 
text to their subject and configured their client side MUA filters to 
mark messages from the mailing list that don't have said blob in the 
subject as read.
