Authenticated Received Chain / ARC

Am I correct to assume that RT doesn’t support ARC at the moment? Are there plans to add it?

In light of the Email sender guidelines - Gmail Help, I was considering creating an extension (or a patch?) to add ARC based on inbound Authentication-Result DMARC headers but would like to make sure I’m not reinventing the wheel.

While still way below the 5,000 threshold, noticed GMail is considering some of the legitimate emails forwarded by RT as spam (mostly automated alerts and occasional new ticket notifications from a queue that has a publicly accessible email address that sometimes receives spam emails).

Any advice would be appreciated.
