I am looking for the easiest and most robust way to remove all user defined

Something like the following, inserted in mailutil, ought to do the trick.
No guarantees. This is just off the top of my head; I haven't actually
tested it. So you may have to do some debugging...

/* What we are about to do here is incredibly evil and utterly
unsupported. Basically, we erase all the keywords from the
