DMARC was not created by Yahoo for Yahoo. They merely spent several months of testing before turning on the reject policy. I have been using it for many months on my private domains & get daily reports of forging attempts as they have been around since before the registrars were allowed to obfuscate or hide domain contact addresses.
There are a couple of ways to use DMARC with mailing lists; http://dmarc.org/faq.html#s_3 Q.v. the Wikipedia entry on DMARC for more history and the orgs that participated in its inception. -Gary _______________________________________________ openindiana-discuss mailing list openindiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
