TOKYO, Aug. 27, 2008 (GLOBE NEWSWIRE) -- Internet Initiative Japan, Inc. (IIJ)
(Nasdaq:IIJI) (TSE1: 3774), one of Japan's leading Internet access and
comprehensive network solutions providers, today announced the release of its
developed mail filtering software for implementing SPF/Sender ID(1) sender
authentication technology on mail systems. To facilitate the adoption of
effective sender authentication as a means of blocking spam with spoofed sender
addresses, the open source software is being offered free of charge to
companies, ISPs and individuals. IIJ is working with Internet Association Japan
(IAjapan) on this release, and the software can be obtained from the following
web site.

- SPF/Sender ID authentication library
- A Sendmail/Postfix mail-filtering software that uses the above
library
Sender authentication requires that both mail senders and receivers take
measures, and with SPF/Sender ID in particular, implementation is easy for the
sender, which accounts for the rapid spread of this technology on the sender
side. However, the receiver requires a separate mail filtering software that
makes it harder to implement, and this has put a damper on its popularity. The
mail filtering software available today consist of either open source software
which are unstable, or commercial software that comes at a price, both of which
have had a negative effect on corporate and ISP adoption of SPF/Sender ID.
IIJ's software was designed and developed entirely by IIJ and is a high-quality
mail filtering software that operates stably even in IIJ's harsh commercial
services environment. By offering this software free of charge as open source,
IIJ seeks to overcome these problems and contribute to the widespread adoption
of SPF/Sender ID on the receiving end. IIJ has partnered with IAjapan to provide
support and documentation to help this software gain wider acceptance, from
corporations to Internet service providers.
IIJ started piloting sender authentication on its internal network in 2005, and
was an early tester and evaluator of sender authentication. In 2006, IIJ applied
its developed mail filtering software to the IIJ4U service for individual users,
and began to offer filtering capabilities based on SPF authentication results.
On its corporate mail security gateway service, IIJ Secure MX Service, IIJ
introduced the capability of adding the results of SPF and DKIM2 authentication.
IIJ intends to make a public release of a DKIM-compatible mail filtering
software and continually improve and upgrade the functionality of this software
to meet corporate and ISP specifications, thus further contributing to the
wide-spread adoption of sender authentication.
On the occasion of this release, IAjapan released the following statement.
Internet Association Japan established the Unsolicited E-mail Measure Committee
in 2004, and we have done all we can to promote anti-spam technology and improve
the legislative environment. IIJ's announcement of the release of its free mail
filtering software will be a great boost to the deployment of the technical
solutions. And it is highly appreciated that IIJ takes an open source approach
to this release. In its future developments, we hope that many players will join
IIJ and IAjapan to achieve global acceptance of sender authentication
technology, which means not only within Japan but also internationally.
Toru Takahashi
Vice Chairman, Internet Association Japan
IIJ will continue to pursue research and development of new technology to build
a safer, more secure messaging environment.
1. SPF/ Sender ID:
An IP-address-based sender authentication technology. This
system validates the originating domain of email by retrieving
valid outgoing mail server information stored in the DNS entry
for the originating domain, and checking for the existence of
the most recent IP address for outgoing mail servers. SPF
(Sender Policy Framework) is the creation of Meng Wong, founder
of U.S.-based Pobox.com, while Sender ID is a combination of
U.S.-based Microsoft's Caller ID for Email and SPF.
2. DKIM:
An electronic signature-based sender authentication technology.
Email senders add an electronic signature to their messages, and
the email recipient references this signature to determine the
validity of an email. It is the result of merging the
specifications for Cisco Systems' IIM (Identified Internet Mail)
and Yahoo!'s DomainKeys.
