As I understand it, sendmail is "handed" an address which is separate
from the To: address in the message, although it may originally start
with that as its base.  If the message makes many "hops", each site
modifies the address that is handed to it (the "envelope"?) in order
to strip its own name from it, the "next" site's name (when the route
gets resolved), and to actually send it to the next site (let's say,
for the sake of argument, as uux rmail).

Are there any circumstances under which sendmail is not given an
address (e.g. by rmail) to work with, and which goes through all the
rewrite rules in sendmail.cf?  In particular, is it ever deemed
correct behavior to use (and munge, which is my problem) the To:
field directly????  My inclination is that this should never happen,
but our site has only UUCP and ethernet transport systems, and it
may not be representative of, say, arpanet mailers.

Thanks for any help.  Let me know if I have muddled the point, and I
will try to get more specific.
