TOKYO, July 17, 2008 (PRIME NEWSWIRE) -- Internet Initiative Japan Inc. (IIJ)
(Nasdaq:IIJI), (TSE1:3774), one of Japan's leading Internet access and
comprehensive network solutions providers, today announced that the integrated
email security solution IIJ Secure MX Service is now compatible with DomainKeys
Identified Mail (DKIM) technology.
DKIM is a sender authentication that enables the recipient of an email to
authenticate the sender of the e-mail through a digital signature attached to
the e-mail message by the sender, and thus determine the validity of the e-mail.
The IIJ Secure MX Service now uses DKIM technology to validate the senders of
the e-mail received by the IIJ gateway server and to insert the results of a
message evaluation into the message header as a score before delivering it to
the customer. The customer can use the score on an incoming e-mail message to
filter the messages at the customer's e-mail client.
IIJ Secure MX Service has been using the Sender Policy Framework (SPF) as its
sender authentication. SPF verifies the integrity of the sender's domain on the
mail address with that of the sender's mail server, which in effect verifies
that each e-mail message was sent by the server associated with that domain. In
contrast, DKIM uses a digital signature to validate the mail message itself.
This method is effective against phishing schemes that alter mail header
information, and it is already in wide-spread use in the United States. SPF and
DKIM can be used together as well to create a stronger anti-spam barrier.
IIJ was the only participant from Japan in the DKIM interoperability test
conducted in October 2007 with the world's major ISPs and vendors, and we
continue to participate actively in these and other kinds of tests to further
the development of sender authentication. Planned improvements for the IIJ
Secure MX Service include automated DKIM digital signature insertion on all mail
messages going out through the IIJ Secure MX gateway server. The IETF is
currently working on standards for expanded DKIM technology, called DKIM
ADSP(*), and as soon as the specification is complete, IIJ will begin
implementing it.
IIJ will be conducting free trial on for this latest feature enhancement as well
as new features added in the future.
