I will strongly hold on to the approach that if there's no strong evidence that the sender (not ISP, not neighbors, but that particular sender) is a spammer, treat them as legitimate. "Innocent until proven guilty". In edge cases, it's always better to let a spam message go through than block a legitimate message. I think mission of everyone who runs a mail server is to facilitate communication. Not to try (with dubious result) "educate" anyone by blocking that communication. I block spammers to protect myself from spam, not to "educate" anyone. Every reasonable person knows that spamming is bad. Even spammers know that. If they're still spamming despite knowing this, nobody is gonna "educate" them. If there's an ISP that doesn't care about their users spamming, nobody's gonna "educate" them too. But still, some user may choose that ISP (maybe because he/she doesn't have any other choice) to host their mail server. He/she should not be punished for what other users of that ISP do. In my opinion it's very bad that many mail recipient nowadays are doing the exact opposite of what I described above, ie. treat senders as "guilty until proven innocent". Basically it's a dead loop, because how in the hell one can "gain a reputation", if any unknown sender (and *everyone* was "unknown" at some point in the past) is initially treated as spammer? No delivery = no reputation, and no reputation = no delivery. Dead loop that hinders the communication instead of facilitating it. If someone doesn't want to receive mail, don't run a mail server. It's simple. -- Regards, Jaroslaw Rafa [email protected] -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
