Mike,

Did you just add dnsbl.njabl.org to the available server lists and not
enable it in the specific domain antispam options? You must add it in every
domain for which you wish the list to be used.

Am not sure exactly what you are attempting to accomplish here, so please
expand upon the problem. Are you trying to delete ALL e-mail that matches
the dnsbl.njabl.org list? If so, you need to add it to each domain
individually via antispam options, then choose "1" as the number of matches
before e-mail is deleted. Alternately, you can put it in the list of trusted
blacklists as well. It will accomplish the same thing.

I would not trust any one, single list. Too many false positives. If you are
trying to set up multiple blacklists, you need to enable them at the server
level first, THEN enable them at the domain level. If you have done so
already, you should check the SPAM logfiles. Set the logfiles for antispam
to verbose, if you want to be able to really find the source of the problem.
In my own case, I had a strange, local routing issue that was not allowing
Imail to properly lookup the IP addresses of the blacklists. Imail couldn't
connect to the lists, and everything was simply passed through the filter
untouched. I needed to check the logfiles before I figured out what the
problem was though.
