It looks like your hammiefilter uses almost the same interface that
mine does, so the integration should be a snap.  Since I can't add and
modify arbitrary headers from within mutt (someone please correct me
if I'm wrong) I'm using one of the flags ("important" I believe) to
indicate an unsure in need of training.

This puts messages scored as spam into the caughtspam folder.  If you
are in the caughtspam folder and type "F" (for false) it will untrain
as spam, retrain as ham, and move it to the mail spool.  If you are in
any other folder it does the opposite and moves into caughtspam.
Unsure messages show up as red in the index; "H" or "S" trains and
removes the flag.  I'm not positive the Unsure flagging works
entirely correctly, it's been a while.

Today, actually.  Now I have time for more important matters such as
ridding my mailbox of spam.
