headers in SMTP is out of scope for this WG.

Chris's approach is reasonable, but I fear it is premature.

The foundational issue here is a trade-off between information hiding
and information disclosure.  Privacy vs. ops support.

I've seen essentially no public discussions, here or anywhere else,
about the technical aspects of this policy tradeoff.

Absent some community-based sense of the underlying technical issues
here, targeting a specification is, in my view, not ready for prime time.
