To lower the risk of a false positive, ASSP could (optionally) ignore a missing PTR when it matches the MX-record. A lot of hosting-providers don't provide reverse DNS on their servers. They aren't run from a private line as they almost always have a (invalid) PTR-record.
In this case the IP of 193.172.235.90 matches the MX-record of Lorentzlyceum.nl JP # cat maillog.txt | grep id-9652-137 Jan-22-08 14:47:32 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> renewing tuplet: (193.172.235.0,lorentzlyceum.nl) age: 3d 17h 18m 16s Jan-22-08 14:47:32 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] recipient accepted unchecked: [EMAIL PROTECTED] Jan-22-08 14:47:32 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] scoring Home Country Bonus NL - Arevo BV Jan-22-08 14:47:32 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] Message-Score: total for this message is -15, added -15 for Home Country Bonus NL - Arevo BV Jan-22-08 14:47:32 id-9652-137 [PTRmissing][scoring] 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] scoring (PTR missing) Jan-22-08 14:47:32 id-9652-137 [SPF] 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] SPF: none (cache) ip=193.172.235.90 [EMAIL PROTECTED] helo=exc.Lorentz.local Jan-22-08 14:47:33 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] scoring (Received-URIBL: pass) Jan-22-08 14:47:33 id-9652-137 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] PB: 193.172.235.0 TotalScore is -25, added -25 for MessageOK Jan-22-08 14:47:33 id-9652-137 [MessageOK] 193.172.235.90 <[EMAIL PROTECTED]> to: [EMAIL PROTECTED] message ok FW_School_Business_cards_ ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
