can't get grep txt file-conditional forward to work

I am trying to do several things to messages that come in:


shell=/bin/bash
MAILDIR=/home/mailarchive

 :0c:   #Preserve a copy of the email
 Mailbox

 :0c   #copy for lurker
 | /var/www/bin/lurker-index -c /var/www/lurker.conf -l galactic -m


# Test if the email's sender is listed
 :0
 * ? formail -x"From" -x"From:" -x"Sender:" \
     -x"Reply-To:" -x"Return-Path:" -x"To:" \
     | egrep -is -f forward
 {
# Forward
 :0
 !user(_at_)domain(_dot_)com
 }

I can not seem to get the condition fo forwarding to work.  Right now it 
forwards everything regardless of the whether it actually matches 
anything in the text file forward or not.  What am I doing wrong.  I 
have looked at tons of sites and worked on this for a while but I can't 
seem to figure it out.

Thanks,
Andy
