What do you think about the defers system ?
Fluffy checks the mail server passing the mail over. Note that this is not the claimed source of the email, but the last link in the chain before it reaches Fluffy. As a result, forged headers won't fool Fluffy.
That's true, but no anti-spam program that I have heard of has been fooled by forged headers like that. Why? Because the only Received: header that can be trusted is the top one, which is added by the local mailserver, which -- guess what? -- adds the same IP that Fluffy looks at.
If the mail passes all these checks, Fluffy checks to see if you have had email from this server before. If it has not sent email within a set period (24 hours, or whatever time you choose to set), Fluffy defers the email for a while. The default is 15 minutes, but you can adjust this if you prefer.
This part is nice -- but if it is so strict that it is knowingly killing some legitimate E-mail (by using a single criterion), I'm not sure how much benefit there would be from the deferral.
Spammers don't try to send email a second time, but genuine mail senders always do.
That's wrong. Today, *most* spammers do not try sending E-mail a second time. But some do, and in the recent past, most did.
The part that I was checking is only the defers system. It looks like a quick and easy (and inexpensive) way to block some spam...
If there is a way to just run the defers system, I think that would work well.
