A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : Extended Options for DomainKeys Identified Mail (DKIM)
Author(s) : D. Otis
Filename : draft-otis-dkim-options-00.txt
Pages : 13
Date : 2005-12-27
This document describes options that extend protections offered by
DKIM. These options include Binding-Advice & Role-Assertion, Opaque-
Identifier, and an In-Channel check. The Binding-Advice & Role-
Assertion offers guidance in isolating the source of a message, in
addition to establishing message signature expectations. The Opaque-
Identifier (O-ID) offers protection from replay abuse and intra-
domain spoofing, even when email-addresses are not associated with
the signing-domain. The In-Channel check provides a means to
mitigate DNS lookups for avoiding possible message replay abuse.

In the body type:
"FILE /internet-drafts/draft-otis-dkim-options-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.
