OK, by popular demand, here is a revised tutorial for
activating RBL Checks with Spamassassin. This has
instructions for both VPS1 / VPS2 platforms.

--------------------------------------------------
TUTORIAL:

Running RBL checks in SpamAssassin 2.5x / 2.6x:


STEP 1: is you have to make sure that the Net::DNS::Resolver  is
installed.

Run the following command in shell:

VPS1:

% virtual spamassassin -D --lint

VPS2:

% spamassassin -D --lint

This will give you a report as to what is running o.k., and
what has problems.

If you don't have Net::DNS then do this:

VPS1:

% unlimit
% vcpan Net::DNS

VPS2:

%perl -MCPAN -e 'install Net::DNS'

After you do this, run the -D --lint tests again to make
sure the Net::DNS module is now correctly installed.

STEP 2:

VPS1:
% cd ~/usr/local/share/spamassassin

VPS2:
% cd /usr/local/share/spamassassin

You will find all the tests that Spamassassin is configured
to run in the file:   20_dnsbl_tests.cf

You can see which tests are active and how they are scored
with this command:

% fgrep RCVD_IN 50_scores.cf

If a score is set to 0 that means that the RBL is currently
disabled.  If you want to enable or disable a specific test,
edit your ~/etc/mail/spamassassin/local.cf file to change
the score.

For example, my local.cf has these commands:

score RCVD_IN_BL_SPAMCOP_NET    4.50

    # This activates and assigns a high score to Spamcop

score RCVD_IN_SBL       0

    # This turns off the checks for the Spamhaus block list

    (Note: The reason I turned this off is that I am running
    a check for this particular RBL via sendmail, rather
    than spamassassin)

You will need to do your own research and monitoring to
gauge reliability of various blocklists for your users.

If you want to add a blocklist that isn't already listed in
the 20_dnsbl_tests.cf, you can use this syntax.

header RCVD_IN_EASYBLACK        rbleval:check_rbl('EASYBLACK', 'blackholes.easynet.nl')
describe RCVD_IN_EASYBLACK      Appears in blackholes easynet
tflags RCVD_IN_EASYBLACK        net
score RCVD_IN_EASYBLACK         1.0

      (DON'T COPY the above recipe exactly. The EASYBLACK
      RBL's shut down effective 12/1/03 - so this is a dead
      recipe. But the syntax would be the same for any
      list.)

If you are running spamd, then you need to restart it for
changes to the local.cf file to take effect.
