[Declude.JunkMail] Conditional Whitelist - Good Use of SPF!
Hi, Despite all the shortcomings of SPF, there may be one GOOD use: Every once in a while I receive requests to whitelist certain sender email addresses or domains - then I explain that we don't like to do that because it would allow any spam that PRETENDS to come from that domain to pass. What WOULD be a good feature, would be an SPF based domain whitelist! It would be a conditional whitelist of senders that will ONLY be applied, if SPF for that domain PASSES.

Andy, Since there is already an SPF Pass, Fail, and Neutral result, couldn't you just create a rule that if the sender passes SPF that you apply a large negative point value? Then you could apply that rule to only the domains that you want to whitelist.

A true WHITELIST would mean that: a) it could skip over all the other tests right from the start b) it would work even if you have some tests that DELETE emails! Your scheme would not prevent emails from being killed outright by Sniffer or similar content tests. -Original Message- From: supp...@declude.com [mailto:supp...@declude.com] On Behalf Of Dean Lawrence Sent: Wednesday, January 20, 2010 9:24 AM To: declude.junkmail@declude.com Subject: Re: [Declude.JunkMail] Conditional Whitelist - Good Use of SPF!
