I mean automatically accepted by postfix, but not automatically forwarded to mailboxes. My idea lies on principle, that if sender have valid SPF record, there is no need to greylist (and delaying mail receiving), but... SPF and greylisting are only one part of mail checking (checking directly in smtpd_recipient_restrictions in postfix). I am using amavis with SA, viruschecking and next supplementary tests (razor, ddc and so on) for scoring mails and then forwarding through MDA to mailboxes.Henrik K put forth on 9/28/2010 12:28 AM:On Mon, Sep 27, 2010 at 03:12:01PM -0500, Stan Hoeppner wrote:Snowshoe spam will most probably pass greylisting too. Better not clutter greylisting database with useless things. Have the blacklists block'em instead.I don't follow your logic here. Yes, most snowshoe is sent from real MTAs, not bots, so greylisting won't stop it. However, dnsbls and local block lists aren't very effective against snowshoe either, although Spamhaus DBL is getting much better WRT snowshoe. I have a local snowshoe cidr table I've been building for 2 years and it works rather well as I see maybe 1 snowshoe in the inbox every two weeks or so. However, most people probably don't have such a local snowshoe blocking list.Umm, what's YOUR logic here? Greylisting won't stop it, dnsbls won't stop it? So I guess it's ok to blindly greylist stuff in case it "happens" to stop it?Of course I'm not advocating folks blindly greylist. I promote super-selective greylisting, and have many times on this list. The point I was making is that SPF is not a solution for making a reject/ok determination as an isolated smtpd test. It's only useful for scoring systems. Greylisting in isolation won't stop snowshoe either. Again, it is useful in blocking snowhoe if used in a scoring system such as SA.So OP's request is valid IMO.Shooting mail straight into the inbox based on an SPF pass is not a valid strategy, but a recipe for more spam in the inbox. SPF is properly used in a scoring system within a policy daemon or external content filter such as SA, same as DKIM etc are.Shooting mail straight into inbox? At some point you seemed to understand the original question, but again you seen to have missed the point? He was asking to bypass greylisting, which is fine. How does that make it STRAIGHT into inbox?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?Maybe I misunderstood the OP's use of the term "automatically accepted".
