Apparently .forward isn't doing its job

On a new server I have ascertained that fetchmail is working.  Dovecot
is also working.  Procmail isn't.

I can't find anything to suggest that procmail actually sees the
messages, so I assume that ~/.forward is the problem.  Could someone
please point out the things that I haven't checked?

ls -l ~/.forward
- -rw-r--r-- 1 anne anne 18 Sep 28 12:16 /home/anne/.forward

cat ~/.forward
|/usr/bin/procmail

ls -al ~/.procmailrc
- -rw-r--r-- 1 anne anne 1099 Sep 28 16:05 /home/anne/.procmailrc

cat ~/.procmailrc
PATH=/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin

#Set user variable
USER=`anne`

#Set user Inbox directory
MAILDIR=/home/anne/Maildir/
DEFAULT=$MAILDIR/


#Set logfile
LOGFILE=/home/anne/pm.log

VERBOSE=YES
LOGABSTRACT=YES

# LOG=" "

:0 * ^From:.*magnatune
$MAILDIR.INBOX.Magnatune/

....

* ^List-ID:.*procmail
${MAILDIR}.INBOX.MailSystems.Procmail/

The logfile ~/pm.log is not being written to.

Where do I look next?

Anne
