Hi: >> "ORDB hatte für den Open-Relay-Check zwei GMX-Adressen verwendet, die nicht auf SMTP-Auth konfiguriert waren." In der eigenen Open-Relay-Definition beschreibe ORDB ein solches System aber als einen Mail-Server, der Nachrichten weiterleite, "bei denen weder der Sender noch der Empfänger ein lokaler Nutzer ist". In den von ORDB dokumentierten Fällen habe es sich aber eindeutig um "local user" gehandelt. <<
May be there IS more to the story, but, it is expected and normal, that anyone who gets listed as an "open relay" will claim that they really were not and that the process was flawed. In reality, ORDB will send a test message to its own server and watch if it gets delivered. If the "round-trip" was successful, then the result is a pretty convincing case of an open relay. Bottom line, if ORDB found a way/trick to relay a message - then a spammer will too. Unless they can show an actual flaw on ORDB's testing method, I go by the assumption that as long as GMX's server allowed for that way/trick they rightfully would have been listed. It is interesting to note that they eventually resubmitted the server (presumingly after closing that hole) and they were de-listed. I do agree, that the lack of a "real-time" operations center of some of the databases (some don't even offer contact forms) does make them somewhat risky to use - but when viewed against the daily benefits, it's a risk worth taking.

Today I've read an article on a german website (c't computer magazine) http://www.heise.de/newsticker/data/hob-27.05.03-000/ In short there's the information that the big freemailer GMX whas listed from Sunday evening to Monday in the ORDB blacklist. GMX some months ago has announced antispam actions since they have the same problem like msn, aol and co. Last Sunday ORDB has tested a GMX mailserver positive as an open relay (even if the method of testing is controversial) GMX was not very happy that ORDB was not reachable over a "fast way" and GMX-Admin's has had to fill out the standard form on the ORDB website asking to be removed as fast as possible. The result: On Monday a lot of mails was not deliverable because other mailservers blocked any connection from GMX (based on the ORDB blacklist) Markus --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
