    We use spamhaus.org: sbl-xbl.spamhaus.org and have been for some
    months without any problems being reported.

    As a result of reading this:

            http://www.spamhaus.org/effective_filtering.html

    we recently added content filtering using the dnsbl milter.

            http://www.five-ten-sg.com/dnsbl.html

    This needed a patch to reap zombies for FBSD, and we also hacked out
    some code to prevent it from checking the nameservers of the URLs found
    in the messages; we found that to be a bit overzealous.

    The install script needed changing, as well. If you're interested, I
    can send you patches that we used to get it working. They really are
    hacks though, so I'd rather not post them here.

    This solution *seems* to be working well for us. YMMV.

    Cheers,

    Jason.
