A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Sender Policy Framework: Authorizing Use of Domains in E-MAIL
Author(s) : M. Wong, W. Schlitt
Filename : draft-schlitt-spf-classic-00.txt
Pages : 48
Date : 2005-1-3
E-mail on the Internet can be forged in a number of ways. In
particular, existing protocols place no restriction in what a sending
host can use as the reverse-path of a message. This document
describes a protocol whereby a domain can explicitly authorize the
hosts that are allowed to use its domain name in a reverse-path, and
a way for receiving hosts to check such authorization.

Send a message to:

In the body type:
"FILE /internet-drafts/draft-schlitt-spf-classic-00.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
