Using Procmail - mail won't deliver to Default

[Lance Hoffmeyer <lanceh@ibm.net>]

in .procmailrc

SHELL = /bin/sh
MAILDIR =$HOME/Mail
LOGFILE =$HOME/_logfile
VERBOSE = yes
LOGABSTRACT = no
PATH =
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin:/usr/bin/mh
DEFAULT=Inbox
#ORGMAIL=/var/spool/mail/$LOGNAME

but mail does not go to Inbox.  I have also tried 

DEFAULT /$HOME/Mail/Inbox
and
#Default

I am getting the _logfile so what have I got wrong in the syntax to
prevent me from getting mail in /$HOME/Mail/Inbox.  There is an Inbox in
/Mail.
