Apologies if I slept through prior discussions on the topic.


E-mail from our L-Soft LISTSERV was recently rejected by Yahoo with the 
following error:



#####@YAHOO.COM

    Last error: 5.7.9 554 5.7.9 Message not accepted for policy reasons. See 
http://postmaster.yahoo.com/errors/postmaster-28.html



I note:



1.       The e-mail error (5.7.9) references the link  
http://postmaster.yahoo.com/errors/postmaster-28.html.

2.       That Yahoo page does not mention error 5.7.9, but references a similar 
error 5.7.4 "Message not accepted for policy reasons."

3.       It appears that Yahoo wants inbound messages signed using DomainKeys 
technology.

4.       Yahoo is the lead inventor of DomainKeys, along with Cicso, PGP, and 
Sendmail.

5.       L-Soft LISTSERV manuals and Yahoo both refer to the website 
http://domainkeys.sourceforge.net/.

6.       When I click on the Documentation and DomainKeys Implementors Mailing 
List links on that page, I get page not found.

7.       A 2007 USA Today Article 
(http://usatoday30.usatoday.com/tech/products/cnet/2007-05-23-domainkeys-anti-spam_N.htm)
 mentions that DomainKeys have not been widely adopted.

8.       A basic Google search for DomainKeys comes up with no recent articles. 
One website (http://blog.wordtothewise.com/2011/09/dkim-is-done/) says that 
DKIM/DomainKeys are dead.





Are the rumors of the death of DomainKeys premature? If not, is anyone from 
Yahoo listening?
