We use uucp, and when we get mail from the outside world, it is
often the case that the From: line doesn't match the Return-Path:
line.  For example, I received a message this morning in which
the lines were:

	Return-Path: <nbires!usenix!uunet!apple.com!timo>
	From: Timo <usenix!uunet!apple.com!timo>

This same thing happens if one of the sites involved is "pyramid",
and at one time also happened with "verdix".

I talked to the folks at pyramid last year, and was told that
it is actually improper for mailers to modify the From: line.

I need to explain to people in my company why they need to be
careful when replying to mail messages from outside.
