I would not be surprised if the "failures" you got on those addresses were actually from the Policy Block List, and thus not necessarily spammers. You might want to further restrict what you consider spammers by testing for a range of values (specified on that http://www.spamhaus.org/zen/index.lasso page highlighted in the previous note). Quote from that page: "Caution: Because the PBL lists normal customer IP space, do not use PBL on smarthosts or SMTP AUTH outbound servers for your own customers (or you risk blocking your own customers if their dynamic IPs are in the PBL). Do not use PBL in filters that do any deep parsing of Received headers, or for other than checking IP addresses that hand off to your mailservers." ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
