Erik Thauvin has replied to Cedric's Spam Challenge.
He talks about the problem that we now have with white lists.
If I say "almaer.com is fine. Let in anything from there", then all of the spam that FAKES the domain almaer.com can get in.
However, this is where reverse MX can come in. When I get the email coming in I talk back and say "This system tried to email using the domain almaer.com", and it errors out.
A Reverse MX type of technology is really needed here. If everyone started to work more with Digital Certificates that could help too (as it would off a nice way to authenticate if the user is foo@bar.com)
