New approach to defeating SPAM

Recommended Posts

Interesting idea, I like it! :) How long do you reckon it will be before someone sues after being caught in one? (Yes I am very cynical)

A good spam solution is TMDA (Tagged Message Delivery Agent)

 

Basically any incoming mail has a automatic message sent to the sender, if the sender replies then the original message gets through to your inbox.

 

As the majority of spam cant be replied to you don't get most spam.

 

It also combines a whitelist and a blacklist. Anybody on your whitelish gets through to the inbox anything on the blacklist is automatically deleted.

 

You can allow anyone who confirms the reply mail gets put into your whitelist etc..

 

highly configurable

Yes, TMDA seems good. But it also feels to me, like playing with fire... Answering to the spammer, and thus validating your e-mail address, is something I won't do.

There seems to be a risk of screwing the wrong person or organization since the spam originates mostly from hijacked or phony addresses, much like a Distributed Denial of Service Attack. See http://www.grc.com for description. They also have a forum for spam and news.grc.com. If domain banning were levelled at hotmail and yahoo for example, you would see fast action indeed. The problem is that so many ISP's would need to cooperate and so many have open relays, that it becomes an impractical idea, although it does work with smaller ISP's. When I was on Sympatico, they spent a good deal of time on the ban list with email bouncing and still didn't plug open relays. Among the open relay blockers is http://www.orbz.org/ , http://www.dorkslayers.com/remove.html , http://www.dorkslayers.com/timeline.html , http://www.ordb.org/faq/ . http://www.sohoskyway.net/supportctr/spam/index.php is an interesting site that describes different approaches to spam.

But most of the time you would not confirm your email address to the spammer

eg the message comes from some_none_existant@address.net or is relayed of some suckers valid address they have hyperlinks on the message to get you where they want you.

 

if a spammer does reply then you just blacklist them.
