[dmarc-discuss] policy overrides and 'what-if'

[Michael Adkins]

Ah, interesting point.  As Paul mentioned, there will be a list of all the
expected override types.  It might take a little more operational
experience before we can conclusively say we've covered them all, but I
think we should make the effort to document an exhaustive list in the spec.

The answer to your question seems like the sort of thing we should include
in an operational guidelines document for domain owners, but I don't think
we've documented them yet.
