As long as you're working...  ;-)

I want a way to re-filter all the mesages in a mailbox, because I often
filter wrong, or add filters at a later date.  (Filters that deliver into
more than one mailbox could cause plenty duplication when re-filtering...)

FYI:

Now, this won't work for remote mailbox filtering, but I currently use
(pretty much straight out of the procmail man page):

cd $DIR

[ -f "$BOX" ] || {
                  echo $0: $BOX: not a file >&2
                  exit 1
                 }

# Not really necessary but...
[ ! -e .filtering ] || {
                        echo $0: .filtering: already exists >&2
                        exit 1
                       }

cat "$BOX" >> .filtering
cat /dev/null > "$BOX"
formail -s procmail < .filtering
rm .filtering

If I was using something other than mbox format I couldn't use formail to
feed procmail messages for re-delivery.
