There is a shared database = called the "Open Relay Blacklist" This is a list of mail servers that = allow spam to be sent through them because of misconfigured security. = They are not neccesarily *sending* spam, but are allowing spam to be = freeley sent through them. Some mail programs can automatically reject = from hosts on the ORB. But basically, the problem is fairly simple to solve. Essentially, all = you need to know is that the mail server is a real, live authenticated = mail server, and not someone trying to hide. Spoofing is tha main = problem, and if you remove spoofing, then you would kill most of the = spam because you could either complain to the originator, or block them. = Or, as you mention, only accept mail from "certified spam free" hosts. The authentication can happen via encryption, or a host of other = methods. Technically, it is not hard, but it is a big = infrastructure/standards thing to actually get in implemented and in = place. >=20 > Ok, I know it is not impossible, can be difficult, yes, but,=20 > sooner or later this would happens, right?

So, why it is so difficult to put an lid on it? >=20 The main problem is that SMTP (email protocol) was never designed to be = secure. It was just a quick thing to get email going. Back in those = days, if you had a one line ad in your sig block, people would jump all = over you. Advertising was strictly forbidden.

It isn't anything like what you are = describing.=20 There is another complication regarding how to classify SPAM. Certainly = porn stuff is clear, and messages that are deceptive are clearly Spam. = But what about an ad from a catalog place where you bought something two = years ago? Is that Spam?
