Abstract:
"  In contrast to other more extensive approaches to deal with
    unsolicited email, commonly called "spam", this memo discusses a very
    simple authentication scheme. It uses marking of hosts in reverse DNS
    (in-addr.arpa zone) to allow the receiving mail transfer agents to
    decide whether the connecting (sending) host is a designated mail
    transfer agent (MTA) or not.

    Despite being a weaker scheme than most of the other proposals
    currently discussed, it can reduce the amount of spam and viruses/
    worms significantly and has the advantage that it can be implemented
    based on existing and well-established Internet technology like DNS
    without any changes to that technology.
