Domain keys for JAMES
JAMES users,
I started looking into using JAMES for my company about 2 weeks ago. I
was unable to find any existing implementations of the Yahoo! Domain
Keys standard in java, so I started working on one.
Is there still community interest in having an implementation of
domain keys for JAMES, or should I wait for the DKIM standard which
will likely replace the current domain keys standard?
Info on both domain keys and DKIM can be found at
http://antispam.yahoo.com/domainkeys.
Sincerely,
Tom Brown

Tom,
digging into the topic, it looks like using a combination of SMIMESign,
IsSMIMESigned and SMIMECheckSignature would do the work.
SMIMECheckSignature would need to be enhanced to get the public key from
the sender domain's DNS, and perhaps SMIMESign should be somehow
adapted, but probably not.
What do you think?

No. I've pinged again.

Did the legal folks ever get back to you on whether or not an
implementation of domain keys can be included?

The current status is that we have identified a problem in the Yahoo!
license, and are pursuing the matter further.

Thank you! Of course it would be really cool if we can include DK
support in the standard distribution of james!

According to
https://datatracker.ietf.org/public/ipr_search.cgi?option=wg_search&wg_searc
h=dkim, DKIM (http://tools.ietf.org/wg/dkim/) is also governed by
http://antispam.yahoo.com/domainkeys/patentlicense1-2.html.

I'll raise the question of the patent license with our legal folks.

From the yahoo website:
Yahoo!'s DomainKeys Intellectual Property may be licensed under either
of the following terms:
* Yahoo! DomainKeys Patent License Agreement
* GNU General Public License version 2.0 (and no other version).
So I believe that we cannot include such code in james distribution but
that a GPL plugin for james could be created.
If this plugin need to extends/reuse SMIME mailets I would be happy to
grant GPL usage for the one submitted by me (there is a compatibility
issue between GPL and ASLv2).
Btw I think that it would be cool to have support for DK even if not
officially supported and distributed under the GPL from another website.

Tom,
I started working on this myself but put it on the back burner quite
some time ago. I have classes that wrap the openssl command line. I
wrote these primarily for testing. I have some code working that
performs canonicalization. And I also wrote some other classes that
do the DNS lookups and the beginnings of a class that does verification.
Let me know if this would be of use.
Vincenzo,
As far is the SMIME classes go, I think they would have to be
extended, not just to get the public key, but also to perform
canonicalization and to understand what headers to use or ignore via
the DK header field.
