These are not downloadable lists.   That would be shooting at a rapidly moving target as thousands of IP addresses and networks are banned and unbanned each day.

These "lists", which are actually databases, are consulted by doing DNS lookups.  Here's an example:

    ================== FIRST TEST ===================

    Lookup 2.0.0.127.sbl-xbl.spamhaus.org
    Expected result success, 127.0.0.2

    Official name = <2.0.0.127.sbl-xbl.spamhaus.org>
    Address length in bytes = 4
    Resolved to 127.0.0.2

    Validation successful

    ================== SECOND TEST ===================

    Lookup 1.0.0.127.sbl-xbl.spamhaus.org
    Expected result failure

    Lookup failed, h_errno = 1 <Unknown host>

    Validation successful

    ================ ALL TESTS PASS =================

Open in new window


If Spamhaus thinks there's a problem with an IP address, you do a DNS lookup for that address with the octets reversed, followed by the database name (in the above, the "sbl-xbl" database), followed by "spamhaus.org".  If there is a response, Spamhaus thinks there's an issue and the low octet of the response indicates the problem.

Most other spam databases work the same way.

Postfix can check these databases automatically.  There are plugins for Apache (mod_spamhaus, mod_torcheck, mod_honeypot) to do IP validation for web server requests.

Side note:  While the Barracuda RBL is free, all other Barracuda services are now by paid subscription.  Check the cost against the benefits before signing anything.

Ok.

How then can we download a copy  of the free "Barracuda Reputation Block List (BRBL)" ?
