The main problem with the munging of From: lines stems from ambiguous
addresses and how each site along the way feels they should handle it
as they gateway.  This is not an easy problem (see Honeyman's recent
paper and accompanying 1.5Mb of AI that figures it out "most of the
time" :-), but most sites take it upon themselves to destroy the
headers.  While correct that 822 does not provide for slapping a
sitename! on the front of the address, normal UUCP conventions dictate
exactly that.

All the ambiguity questions have been asked, but only one answer
remains -- make all sites do routed addressing, so everyone can munge
them appropriately, or use domain addressing.  Which do you think is
the more reasonable advice ...?
