Is this for real?

In Outlooks instructions on how to get email delivered : Policies, Practices, and Guidelines (Section 4) you find:

“Email sent to users should include Sender ID authentication. While, other forms of authentication are available, Microsoft currently only validates inbound mail via SPF and Sender ID authentication.”

Is this for real, or should it say SPF & DKIM ?

I’ve confirmed with my contacts at Microsoft that the help document is outdated and scheduled for an update in the future. SenderID is no longer used at just SPF, DKIM, and DMARC.
