I've been adding dns blacklists through the courier webadmin with great results. Wanted to add lashback to the list, and found this in their info:
if you wish to check whether 192.168.1.100 is listed in the UBL, you would perform a DNS lookup on 100.1.168.192.ubl.unsubscore.com Is this how the web configured DNS blacklists work or do they simply make a reverse DNS lookup on the IP address? I was hoping to migrate the blacklist lookups to a localhost BIND and effectly use it as a proxy for courier to make one single rdns lookup on, but if they all operate like lashback, then thats not going to work with multiple dnsbl's Lisa. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
