This is taken from procmail3.06/examples/advanced.  I chose not to go
with the h flag.  Flag meanings are added where the flags are
different.  Also, if you're running 8.6.9, you might want to add plus
addressing.  The directions in the advanced file don't work, since
8.6.9 gives you many routes to get to Mlocal.  Warrantied to work or
your money back.



# flags different are
#  S dont reset ID
#  !h preserve uppercase in hostname
#  P need return-path header
#  f delivery agent adds -f to argv
#  r delivery agent adds -r to argv
#  m multiple recipients possible

Mlocal, P=/software/bin/procmail, F=lsSDFMPfn, S=10, R=20/40,
        A=procmail -a $h -d $u

# replaces:
# Mlocal,       P=/bin/mail, F=lsDFMrmn, S=10, R=20/40,
#               A=mail -d $u

---------plus addressing -----------------

	The following changes seem to work for me.  All lines with a
++ were added manually.  The others are there as reference points.
