Where can I find out about domain keys?

[Martin Gregorie <ma...@gregorie.org>]

A friend tells me that some mail I sent to him at xtra.co.nz (now a
Yahoo subsidiary) was flagged as spam. He sent me the headers, but all
it shows is:

X-Apparently-To: my.friend@xtra.co.nz via hhh.hhh.hhh.hhh; 
	Thu, 21 Feb 2008 15:46:00 -0800
X-YahooFilteredBulk: 77.75.108.10
X-Originating-IP: [77.75.108.10] Authentication-Results:
	mta105.tnz.mail.aue.yahoo.com 
 	from=gregorie.org; domainkeys=neutral (no sig)

I wrapped the lines to suit the e-mail. These are the only indications
of why my mail was treated as spam. What is this domainkeys of which
they speak? 

Can anybody point me at an explanation? Words or a URL would be equally
good.


Thanks,
Martin

Quoting Yahoo:

"DomainKeys is yet another way Yahoo! brings untold misery and grief 
to email forgers
  everywhere. Without boring you with too many details, it's an 
Internet standard
  developed in large part at Yahoo! that lets us confirm whether 
emails are really from
  their claimed domain."
