One of the early blacklists was called SPEWS and it had a similar model as what it appears this one is using, where it decides to ban and tire network as ounative punishment for one spammer. They also did not have a good track record of dealing rationally with people who were not spammers and generated a lot of ill-will. I was on a fixed IP on a class C that was listed by slews because a user hacked into an entirely different system on a different domain and sent out a bunch f spams. The ISP shut down the connection quickly, leaned the system, and the spam stopped. The entire class C was listed for months. <https://en.wikipedia.org/wiki/Spam_Prevention_Early_Warning_System> I'd check mxtoobox and check your blacklsits listing there. If there are other non FABEL hits, then definitely try to fix your setup If it's just label, move along. > I'm not sure what the "silent drop" is about... > Some recipient server is setup to pretend-accept your emails when you > are listed on that DNSBL ? Some setups do this. Certainly before psotscreen if I received mail and SA scored it above a certain level the mail was effectively silently dropped. (Not in point of fact, it was recoverable for a week, just in case, but it was not delivered to the target account). I've seen a lot of comments about lack or response, lack of consistency, and lack of removal from this RBL. Sadly, there's nothing you can do about a incompetent RBL or the people who use it. -- 'People need vampires,' she [Granny] said.
