my.com adds reject DMARC policy starting March, 1 2016
 

Starting March, 1 2016 Mail.Ru begins to implement restrictive DMARC policy for public mailbox domains with my.com being the first domain to publish p=reject policy. Please make sure to update configuration if you need special handling for DMARC-restrictive domains.

In future, policy will be updated for other Mail.Ru public mailbox domains, including mail.ua, bk.ru, inbox.ru, list.ru and finally mail.ru.
