As I can inject my message directly to GMX, I'm Cc'ing Helmut Schneider.

GMX are responsive compared to other freemailers such as web.de which are utter crap. GMX allow the user to configure which "Spamschutz" (literally "spam protection") settings he wishes to employ, but there are some issues: * GMX try to persuade users to go with "the GMX recommended settings", which is "all filters on". * Some filter settings (all are configured through a web interface) require JavaScript. * GMX have split their filters into seven categories, but merged several services into the same option: 1 The "Spamserver-Blocker" is actually an SPF implementation, accompanied by a GMX internal list. Unfortunately, SPF is inseparable from the GMX internal list of SPF policies (AOL, Hotmail and stuff). HELMUT - the best bet is probably to disable the Spamserver-Blocker. (You need to personalize your Spamschutz settings) 2 The "Globale Antispam-Liste" is a mixture of: a - a blacklist of known spam sites (it's unclear how this overlaps with the "GMX Team Antispam-Liste" b - an open relay blocker c - a dialup blocker d - a blocker for SMTP servers whose IP cannot be resolved via DNS PTR records. This is all documented behind the "Hilfe" popups (Hilfe = help), only users need to be made aware of such, and they never see these options when using the GMX standard settings. For those who can read German, the full documentation is at <http://faq.gmx.de/optionen/email/antispam/index.html> An English translation of who can send to GMX.de is at <http://faq.gmx.de/optionen/email/antispam/4.html> > <jumper99@gmx.de>: host mx0.gmx.net[213.165.64.100] said: 550-5.7.1 {mx021} The > recipient does not accept mails from 'FreeBSD.org' over foreign > mailservers. 550-5.7.1 According to the domain's SPF record your host > '81.196.204.98' is not a designated sender. 550 5.7.1 ( > http://www.gmx.net/serverrules ) (in reply to RCPT TO command) And this looks like the "Spamserver-Blocker" in action. Personally, I have both The Spamserver Blocker and currently also the Global Antispam list off. I might turn the latter back on some day though, if traffic becomes too much to handle for after-the-fact filtering. HTH, -- Matthias Andree
