I've always considered having to check your spam for false positives to make having anti-spam filtering a waste of time. Not to mention it being a denial of service if it does snaffle up real mail. Richard Vickery: > I wonder what Google's secret is? Well, when you're a huge service, receiving thousands of spam, much of it near-identical, and from common sources, it becomes much easier to identify spam as being spam. And some services are better at that, when they actually want to reduce spam, unlike some others that don't appear to give a damn. Even on a small self-run service, if you expose a honeypot address, it'll get spammed along with the real addresses. Using the honeypot received messages as spam identifiers, you can 100% identify identical messages sent to the other addresses as being spam (unlike other far less positive identification methods). That can knock out a huge amount of spam, in a very simple, and reliable, way. Other identifiers (HTML mail, attachments, bad grammar, broken mail formatting, messages not personally addressed to you, et cetera), falsely identify a horrible amount of real mail. And almost all commercial mail that I have personally subscribed for gets falsely identified, list mail gets it, mail from friends who couldn't type or spell properly to save their life... To make it worse, when your mail service provider does the identifying, they often give you no controls to reign their anti-spam software in (you can't adjust the thresholds and ratings, nor can you give it back spam and ham for it to learn). -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
