[AMaViS-user] OT: Where to find info on DNS based spam prevention

[Turgut K. <tu...@eg...>]

I had recently heard of a new attempt to stop spam by broadcasting the
hosts on which *your domain* sends email from; like for egenet.com.tr , I
could define a handful of servers that transmit email out, and each site
receiving mail from egenet.com.tr verifies that the email actually
originated from one of these hosts, and not some &*^*&^* sending stuff
from blah-dsl.verizon.net pretending to be from egenet.com.tr..

Does anyone know where I can find more info on this?
Thanks! -turgut
