[mew-int 3010] Lost refile system

Hi,

Somehow I seem to have lost my refile functions :-)

I have what appears to be a mew refile from alist (that has
been running for a number of years) but the only option I
get offered now is

+Maildir/fgs/

In an attempt to solve the problem I have added the last
three lines to what I thought was the relevant section of my
~/.mew.el

  (setq mew-mailbox-type `mbox)
  (setq mew-mbox-command "incm")
  (setq mew-mbox-command-arg  "-a -d /home/fgs/Mail/Maildir/fgs -i /home/fgs/Mail/inbox")


; next 3 lines added to try and solve problem (no joy)
(setq mew-refile-guess-by-folder nil)
(setq mew-refile-ctrl-multi nil) 
(setq mew-refile-guess-by-from t)

Would someone who knows far more than me please correct me
in the error of my ways.

Many Thanks,


Francesco
