Hi,

Per the boilerplate….

"I have reviewed this document as part of the Operational directorate’s ongoing

effort to review all IETF documents being processed by the IESG.  These comments

were written primarily for the benefit of the operational area directors.

Document editors and WG chairs should treat these comments just like any other

last call comments.

”

This is a brief, straightforward document and I believe it provides adequate
guidance to implementers that it will serve to enhance interoperability, as
intended.

Mail policy handling is of course extremely controversial but I found the
shepherd’s writeup helpful in understanding the specific issues around this
document and how they were resolved. It appears to allow flexibility to
implementers who want to use these codes without requiring anything in
particular of those who don’t. Specifically, it appears to allow more
information about mail policy to anyone who wants to deploy now, while
deferring extensions that might be applicable to DMARC to that WG.

Whatever your feelings regarding proper mail handling policy, this looks useful
in allowing operators to signal whatever it is they do in more detail.
