help with content filtering

Hey, I'm having some trouble getting postfix's content filtering to
work correctly. I'm running FreeBSD 4.8, I built postfix 2.0.6 out
of FreeBSD's ports tree.

Postfix functions correctly until I follow the steps for simple content
filtering in FILTER_README. When I try and send mail either through the mail
command or through smtp, I end up with generating lots and lots of emails to
the MAILER-DAEMON (a mail loop?). I'm guess would say that I have something
wrong in the either master.cf, or main.cf, but I've followed exactly
the instructions in the filter readme. I'm even running it through the
sample shell script described in FILTER_README.

I can get the shell script to write the emails to /tmp, but I get the mail
loop when I called sendmail and resend the message.

This is what my master.cf looks like.
smtp inet n - n - - smtpd
  -o content_filter=filter:dummy # I added this line.
filter unix - n n - - pipe # and this one
  flags=Rq user=filter argv=/home/jasapp/src/mail1.sh -f ${sender} -- ${recipient} # and this one

In my main.cf, I've set these values.

myhostname = fmail.blah-blah.org
mydomain = blah-blah.org
myorigin = $myhostname

Ideally, I'd like to run all my mail through this computer, have it filtered
for content, and then sent with a transport to my primary mail server.
I've turned of the transport for the time being, but just so you know.

It's likely I've forgotten some information about my configuration. If
that's the case, please ask.

Thanks,
Jeff
