This may be an idea that has already been proposed. If so, sorry for
the duplication. I've long been of the opinion that spam can be
reduced significantly by denying spammers the use of forged domain
identities. I believe this idea will go a long way toward that goal
without adding much data overhead to typical mail transactions between
mail servers or clients. I would appreciate an expert critique.
The objective of this strategy is to reduce or eliminate emails
accepted for delivery to an electronic mail user which originate from
a fraudulent sender identity. In turn, attribution of unsolicited
emails to a valid email sender identity facilitates enforcement of
policies to forbid or control the sending of unsolicited emails to
third parties.

Many RMX-type proposals are geared towards the same goal and accomplish
it with less trouble. See:
