I look forward to your paper on "the end to end concept, and
why it doesn't
apply to email" ;)
I think the problem here is that people invoke something they think
of as 'the end-to-end principle', but actually isn't.
from <http://web.mit.edu/Saltzer/www/publications/endtoend/
endtoend.pdf>:
-----
. . . functions placed at low levels of a system may be redundant
or of little
value when compared with the cost of providing them at that low level.
-----
*That* is the actual 'end-to-end principle'. The imposition of
hierarchy in application-layer email routing (or DNS infrastructure,
etc.) has nothing to do with the actual end-to-end principle, except
as a good example of honoring it.
