I can't seem to locate the "reason" page. I see nothing that says this domain was listed due to, ahem, creative use of SPF. It's probably listed simply due to trap hits, which, TTBOMK, is what generates 99.999999% of Spamhaus listings. If Spamhaus is creating preemptive listings due to SPF games, or any preemptive listings for that matter, I'd love to have that confirmed. -- Stan > -------------------------------------------------- > From: "mouss" <mo...@ml.netoyen.net> > Sent: Sunday, September 26, 2010 1:38 PM > To: <postfix-users@postfix.org> > Subject: Re: SPF and greylisting conditioning > >> Le 26/09/2010 12:08, Stan Hoeppner a écrit : >>> Michal Bruncko put forth on 9/26/2010 4:24 AM: >>> >>>> It is possible in some way to configure postfix, that SPF Passed mails >>>> will be automatically accepted with postfix without greylisting? >>> If I may be blunt: this is a really dumb idea.
