This is not unique to porkhash, many if not majority of proposals
either
directly or indirectly rely on source or some central server being
reachable for confirmation (all certificate based proposals, my
callback
verification proposals, RMX - have to have working dns server, etc.)

True.

However, one notable difference is that RMX and similar ideas make use
of the one central server (DNS) that must necessarily *already* exist in
order that one can even receive mail in the first place.

This is a qualitative difference from having to set up some additional
server, though the exact flavor and degree of that difference isn't
clear (to me at least).
