Apologies if I slept through prior discussions on the topic.
E-mail from our L-Soft LISTSERV was recently rejected by Yahoo with the fol=
lowing error:
#####@YAHOO.COM
Last error: 5.7.9 554 5.7.9 Message not accepted for policy reasons. Se=
e http://postmaster.yahoo.com/errors/postmaster-28.html
I note:
1. The e-mail error (5.7.9) references the link http://postmaster.ya=
hoo.com/errors/postmaster-28.html.
2. That Yahoo page does not mention error 5.7.9, but references a sim=
ilar error 5.7.4 "Message not accepted for policy reasons."
3. It appears that Yahoo wants inbound messages signed using DomainKe=
ys technology.
4. Yahoo is the lead inventor of DomainKeys, along with Cicso, PGP, a=
nd 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 Mail=
ing List links on that page, I get page not found.
7. A 2007 USA Today Article (http://usatoday30.usatoday.com/tech/prod=
ucts/cnet/2007-05-23-domainkeys-anti-spam_N.htm) mentions that DomainKeys h=
ave not been widely adopted.
8. A basic Google search for DomainKeys comes up with no recent artic=
les. 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?
