blocking spam with 2.6

[Joey Maier <maierj@home.com>]

Synopsis: 	can't get my new sendmail.cf file to pass the spam 
		rejection test at http://mail-abuse.org/rbl/usage.html
Details:
I have a 2.6 box running sendmail 8.9.3 for our outgoing mail.  I'd
like to also direct incoming mail to this box and use the MAPS rbl 
to reject spam before forwarding the email on to our primary mail
server.  The MAPS-rbl web site at http://mail-abuse.org/rbl/usage.html
says:
=====================================================================
Sendmail version 8.9 is delivered with optional RBL support. Simply add:

        FEATURE(rbl)

to your sendmail.mc file 
=====================================================================

I copied  /usr/share/sendmail/cf/openbsd-proto.mc to
/usr/src/usr.sbin/sendmail/cf/cf/config.mc, then added FEATURE(rbl)
to it.  The resulting file looks like this:

=====================================================================

I "compiled" my config.mc file using the m4 instructions here: 
http://www.sendmail.org/m4/intro.html 

My command string was:

	m4 -D_CF_DIR_=../ /usr/share/sendmail/m4/cf.m4 config.mc > config.cf

There were no errors after this command.

I then tried the sendmail/rbl test at http://mail-abuse.org/rbl/usage.html
to make sure this config file was functional.  It failed that test
=====================================================================
relay# sendmail -bt -C ./config.cf
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> .D{client_addr}127.0.0.1
> Basic_check_relay <>
rewrite: ruleset 192   input: < >
rewrite: ruleset 192 returns: OK
> .D{client_addr}127.0.0.2
> Basic_check_relay <>
rewrite: ruleset 192   input: < >
rewrite: ruleset 192 returns: OK
> relay# 
=====================================================================

Is anyone out there using 2.6 OpenBSD/sendmail 8.9.3 to block spam?
If so, what method are you using?  If you are doing this via the
'FEATURE(rbl)' parameter in a sendmail.mc file, do you see a problem 
with my file shown above?

Any help with this would be greatly appreciated.

Thanks.
Joey
