A New Internet-Draft is available from the on-line Internet-Drafts directories.
Title : SPF DoS Exploitation
Author(s) : D. Otis
Filename : draft-otis-spf-dos-exploit-00.txt
Pages : 10
Date : 2006-4-17
This document describes an email induced Denial of Service threat
from SPF script used to evaluate the association of a source domain-
name with the sending-system. The SPF script attempts to establish
the domain-name association through the construction of an extensive
IP address list of all sending-systems. Expectations of an
association have become problematic, as message handling might be
negatively affected without an apparent domain-name relationship
discovered between the sending-system and either the message envelope
or the message itself.

In the body type:
"FILE /internet-drafts/draft-otis-spf-dos-exploit-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.
