Greetings.

Issue 144 has been opened for the question of what to say about ARC (RFC
8617) in the context of indirect mail flows, a la Murray's example text
from this post
<https://mailarchive.ietf.org/arch/msg/dmarc/v5NMVIZqvRuEfopf7gc0Q1i4Ywo/>:

"One possible mitigation to problem X is [ARC], which provides for a
mechanism to demonstrate 'chain-of-custody' of a message. However, use of
ARC is nascent, as is industry experience with it in connection with DMARC."
