BUT there is no envelope sender re-writing for (in sendmail parlance):
	- aliases without list owners
	- .forward forwarding

Should there be?  It would be a different world.
While that doesn't rule out adoption of RMX, it does make even
its adoption have pretty big impact on everyday normal practices.


P.S. I have now twice succumbed to the temptation to add
to the high-volume small-topic flood.  Now it's out of my
system, and I see the wisdom in Paul Judge's trying to move
the discussion toward longer and systematic drafts rather
than point-by-point reaction.  So I'll be quiet for a while.
