RE: Opening Debate on SPF vs. SenderKeys2004-08-23 06:12:43On Mon, 23 Aug 2004 15:32:56 +0300, Andriy G. Tereshchenko wrote Wrong. In case if you are using non-SPF aware ISP you must be able to perform email filtering in your MUA. You can check IP address from Received: against SPF records and move forgery to "Spam" folder. This is dangerous. Your MUA may be retrieving that mail days or even weeks after it was sent. The SPF record that was in force when the mail was sent may no longer be the same as the one you're checking against.
