That'd be handy.  I wouldn't mind seeing a patch for that, or helping if
necessary (though I should be careful about volunteering time since I'm
starting a new job in September and haven't a clue how much time I'll
have... there's still documentation I want to write.)

On a related note -- have other people been having trouble with
challenge-response using susbscribers on their lists?  Linuxchix has had
some "Dear grrltalk-bounces" messages which are kinda annoying.  We can't
really take the time to jump through those hoops and read every uncaught
bounce, so we've just asked people to whitelist us themselves.
