I undestand now that this working group has been intentionally chartered

The IETF limits itself to things used over the public internet.

How to spool
mail on disk is out of scope, and now to operate on the spooled mail is,
too.
AIUI spooling does not imply that it's stored to disc, just that the
SMTP transaction has completed and that the mail has been committed to
permanent storage.
however, the limit of the end of the SMTP transaction is an arbitrary
restriction based on a particular mail server architecture. there are
many ways that mail can enter a system over the public internet before
final delivery. the working group documentation is anything but clear
on the point that this working group is limited to the consideration
of filter a single protocol (SMTP).
