Procmail can delivery, but that is it

Hi Everyone,

I installed Procmail for the first time.  I want use it as a filter to
separate large emails from the others and send notice to the receipient that
a large email is arrived.  However, I can only get procmail to delivery the
emails but the not the notice message.  Can you give me a hand?

Here are my details

Platform:                       Debian Linux 2.0, Sendmail 8.9.1, Procmail 
v3.11pre7
Sendmail setting:               I have tried all combination of 
MAILER(procmail) and
FEATURE(local_procmail)
Procmail setting:               content of file /etc/procmailrc is

   LARGEFOLDER=/var/spool/mail-large
   LENOTICE=/etc/mail/large_email_notice

   :0:
   * < 2000
   $ORGMAIL

   :0 c:
   $LARGEFOLDER/$LOGNAME

   :0
   | $SENDMAIL $LOGNAME < $LENOTICE

Your help is greatly appreciated.
