using procmail for multiple domains

thanks for the mail.  i've experimented with your approach to no
avail.  unfortunately, $1 and $2 don't seem to get the sender and
recipient.  i've added a domain multihost.com with the following
procmail file (which is referenced appropriately in my mailertable)

VERBOSE=yes
LOGFILE=/etc/procmailrcs/logs/multihost.com
FILE="$0"
SENDER="$1"
RECIPIENT="$2"

:0
* RECIPIENT ?? foobar
! -oi rramstad+foobar

:0
* RECIPIENT ?? rramstad
! -oi rramstad

when i try to send to it, i get the following:

graham# mail -v rramstad(_at_)multihost(_dot_)com
Subject: test
EOT
Null message body; hope that's ok
graham# rramstad(_at_)multihost(_dot_)com(_dot_)(_dot_)(_dot_) Connecting to 
/etc/procmailrcs/multihost.com via procmail...

when i examine the logfile i get

graham# tail /etc/procmailrcs/logs/multihost.com 
  Folder: **Bounced**                                                         0

  Folder: **Bounced**                                                         0

it appears that $0, $1 and $2 aren't set properly.  FILE should be
"/etc/procmailrcs/multihost.com".  i'm also using procmail as my local
mailer as well and the meta argument + passed in via -a works great
(and is available as $1).

from my sendmail.cf (mailertable uses the procmail mailer)

Mlocal,         P=/usr/local/bin/procmail, F=lsDFMAw5:/|@SPfhn, S=10/30, 
R=20/40,
                T=DNS/RFC822/X-Unix,
                A=procmail -a $h -d $u
Mprocmail,      P=/usr/local/bin/procmail, F=DFMmShu, S=11/31, R=21/31, 
T=DNS/RFC822/X-Unix,
                A=procmail -m $h $f $u

note that these are both defaults from using the m4 configuration file
generation stuff in sendmail-8.7.1.  i'll gladly share any fixes with
Eric Allman.

i'm using procmail-3.10.
