>"The biggest problem is We have no idea when it is happening, or if there are complaints, which messages are actually true spam, and which messages are just "legitimate marketing" that look spammy."
Is there a difference? Spam includes UCE (Unrequested Commercial Email). Unrequested marketing junk *is* spam. I report it as such and ban most mail servers that send such stuff to my users. When I first started doing that many years ago, the very first to be banned, permanently, was Constant Contact. And boy were they pissed! They actually tried to tell my users we were doing something wrong and went over my head to try and be removed (and the CEO laughed at them). Now I ban several hundred such marketing houses.
>"Nobody really sends detailed abuse complaints anymore or provide any data that could be meaningfully used for reliable spam content identification without false positives. They just put IP addresses straight to blacklist"
The word "nobody" is pretty strong. I report *every* spam I get, in detail, to spamcop. Thankfully it is only a few messages a week that slip through, but I take the time to do it.
You might not like RBL's, but they are a keystone to our anti-spam. We don't do automated content examination or even ratings at all. Just greylisting, country banning, several RBL's, dropping messages with improper headers, checking that the domains on the Email server and sender are actually valid, and our own blacklist (coupled with a whitelist for both filtering and greylisting for those places that we consider mission important).
None of that requires more than F-15s to solve, and lots of politics. Something that may be beyond your capacity to understand.
Why do you need an F15 to solve attacks made with Twitter?
the actual enemies we have now use twitter and guerilla tactics
He is facing persecution for practicing journalism. Open your eyes
No, he's facing some heat for Sweden over dodging investigators looking into his alleged sexual abuse of two women.
Assange wasn't going to prison in Sweden, he was going directly to Gitmo, without trial, or habeus.
Where - in that tween fantasy novel you're writing?
I teach computer science, and I occasionally get students asking how they could work for a living and still be able to travel, go outdoors, etc. and not be stuck in a cubicle. Do you have any advice for them, such as how to find jobs or clients to work on? How did you get where you were today?
Help me, I'm a prisoner in a Fortune cookie file!
