Georbl: Individual Country DNSBL Zones
I’ve added individual country zones to georbl.info. If you’re only interested in one zone, or are using it with something that doesn’t support TXT lookups (postfix without patching?) you can perform lookups with less hassle.
If anyone has some config examples for other MTA’s, or knows if postfix will support TXT lookups, please let me know. Otherwise, I’ll write something up later myself.
