Users shouldn't be running their own smpt server on a DUL. That's why they are listed. If they used their ISP's smtp host like they are supposed then it would be an issue. Users on DULs shouldn't even run their own smtp server since they can't even keep their systems patched and maintain sufficient virus defs.
As for your example, all the other guys are labeling it as open proxy/open relay. Sorbs has a DUL database and since it's DUL, it goes in their DUL database and their open-relay database. So if 6 RBLS have it as an open-relay then you can bet that it probably is. You could test it openness if you don't believe them -----Original Message----- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Jens Benecke Sent: Thursday, February 05, 2004 4:43 AM To: [EMAIL PROTECTED] Subject: Lost of FPs because of IPs listed in DUL + "open Proxy" Hi, this seems to be an emerging problem with some RBLs (e.g. SORBS). There are seemingly lots of dialup IPs listed in SORBS 'open proxy' and 'open relay' database, which belong to dialup users. Those users may once have had an insecure machine or a virus, but now completely DIFFERENT users get punished just because they happen to have received the listed dynamic IP from their ISP. I rely on RBls quite heavily (about 50% of my mail input is blocked by RBLs, and lots of SPAM that did not come directly via is scored based on RBL information), but I begin having my doubts. IMHO dialup IPs should not be listed in "open proxy" or "open relay" RBLs for months (as the case with e.g. http://openrbl.org/#213.39.202.12) Any ideas? -- Jens Benecke (jens at spamfreemail.de) http://www.hitchhikers.de - Europaweite kostenlose Mitfahrzentrale http://www.spamfreemail.de - 100% saubere Postf�cher - garantiert! http://www.rb-hosting.de - PHP ab 9? - SSH ab 19? - g�nstiger Traffic
