Lee’s “Shooting The Messenger” should be shouted around at least as much as Paul Graham’s “A Plan For Spam” was. It’s an excellent rebuttal of the the growing idea that SMTP needs be replaced by a less spam-friendly protocol: There’s little wrong with the protocol, but the behaviour of servers needs to be tightened up so that spam never gets delivered in the first place. Lee comes up with a solid list of tactics that modern MTAs should employ.
That said, a caveat: I’m scared of relying on blacklists until the behaviour of those lists is similarly tightened up to avoid episodes like this one. And, though nearly everyone disagrees with him, it’s still worth reading what Gilmore has to say.
