Email Caller ID?
It seems the battle against spam is spawning a few unholy alliances . What they miss is we have Email Caller ID now in a couple of forms.
One is called DNS “reverse lookup”. If I could reject all email coming in from that server named “Unknown” (a numeric address without a textual domain.com address) I’d reject thousands of messages a day. I know, I tried it once and pissed off several people….
The other is called TLS which involves too lengthy an explaination to get into at 2AM.
But my point is if email server operators cannot even get their DNS setup correctly so that their IP addresses “reverse lookup” how are they going to do with some new fangled system which will surely use some sort of public key system (which TLS does) which tend to be even more difficult to configure.
And, why are we creating a whole new layer that needs to be deployed and managed when we’re not capitalizing on capabilities and technology that are already out there?
This new-fangled-silver-spam-bullet may very well sell software and possibly (hopfully from MS & Sendmails perspective) lock out those not running MS Exchange or Sendmail mail servers.
