We'd like to add an option to Mail so that it will use the From_ line
rather than the frequently incorrect From: line when users reply to
messages (as more and more intermediate uucp sites adopt the convention
that they not modify the From: line, more and more users here have been
requesting that we "fix the broken 'r' command".  Changing Mail seems
to be the easiest and most reliable alternative.  We do some path
short-circuiting in sendmail, so using the path in the From_ line ought
not to send a mail message too far astray.  In fact, no farther astray
than the message that it's in reply to).

This is on 4.3BSD and SunOS 3.x/4.0 systems.
The changes look easy enough to make (add a check for a new variable,
say, "replyfrom_", and modify the *resp* and name1 routines), but I've
learned never to underestimate the side effects in the Mail source code.  Has
anyone else done this?
