Added to the roadmap (https://products.office.com/en-us/business/office-365-roadmap) for tracking. As mentioned earlier, we’re also looking very seriously at Authenticated Received Chain, which is in draft, but has good momentum for adoption. We hope to report back soon on that as well.
If you’re interested in signing your tenant up early to help us test this out, be sure to give us your email address so you can receive an invitation when we’re ready!
ARC is also coming soon, though I have no date to provide at this particular time. SRS is rolled out to nearly all tenants, but is on hold for some while we finish ARC. Stay tuned.
