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. Glenn REid {decwrl,glacier,sun}!adobe!greid -- You have new mail.
