Hello, a while ago Emmanuel Dreyfus predicted that SPF will become useless quite quicky. Here is the proof: Mar 23 18:11:41 *** sm-mta[22869]: j2NHBe7b022869: from=<Control-1066-82345335-Vis@...>, size=6349, class=0, nrcpts=1, msgid=<82345335.230305085833.1066@...>, bodytype=8BITMIME, proto=ESMTP, daemon=MTA, relay=client230.beta-ca.bsm1mx.com [69.25.109.230] And here the SPF records for the domain "eblue-cten.com": eblue-cten.com text = "v=spf1 ip4:69.25.109.0/24 ip4:72.5.1.0/24 ip4:208.184.55.0/25 ip4:64.125.188.0/25 ip4:64.125.87.0/24 -all" It seems that SPF got useless even before it got widely adopted. I guess I'll have to disable SPF support in my "greylist.conf" soon. Kind regards -- Matthias Scheler http://scheler.de/~matthias/
