We have some student machines on campus which for most purposes do not need to
be able to resolve host names external to the campus. However, when the staff
members using those machines post overseas the return address in the 'From '
line is not fully-qualified, and this seems to make it unreply-able to some
mail systems. A typical header follows :
From darrell@bond Mon Sep 10 10:17:57 1990
Return-Path: <darrell@bond>

As you can see, I've been able to hack the line beginning with 'From:' so that
it looks like I want it to, but I have never been able to alter the line
beginning with 'From '. Can anyone explain the difference between the two,
and possibly explain how I can control what appears in it ? Why do some mail
systems reply to the 'From:' line, and others to the 'From ' line ?
Please reply by email, I can summarise if interest is shown.
System: Sun 4/20's and Sun 4/65 running SunOS 4.1 All running standard
