IF all Bitnet mail was delivered using (B)SMTP (i.e., an envelope instead of a header) AND IF LISTSERV left the "To:" field pointing to the list, THEN it would not need to insert a "Sender:" to identify the list, so "Sender:" could then point to an error delivery box. ALSO, "Reply-To:" would not be necessary, because a simple REPLY command would then reply to the sender, and REPLY ALL would reply to the list. Just like on the Internet, where it works well except for error delivery notices. This would solve the annoying problem of postings stating "reply to me" where the sender doesn't insert a "Reply-To:", and therefore LISTSERV generates one pointing to the list, and most of the replies then go to the list. And since everyone would get an identical copy of each posting, the DISTx code might be much simpler, and it might also be much easier to save more network bandwidth.
