This message is from the T13 list server.

Warning: This has *NOTHING* to do with ATA/ATAPI (but its fun
anyway)...

I agree...

Sender: is *NEVER* used to determine the actual From: or Reply-To:
address. RFC822 is very clear about this. Sender: is expected to be
the name of a mail handling agent - that could be a person (different
from the email address of the person that composed the message) - it
is normally the name of some email server machine (not a person, not
even a valid email address). There is also a header field in most
email called Return-Path: but it is frequently not a real email
address.

But there are two parts to this... The first part has to do with what
kind of email list we have and the second part is about poorly
designed email client software.

First, the list type: Generally email lists fall into two types -
broadcast or discussion list. A broadcast list has the primary use to
send info one way - from one source to many readers with no followup
email expected. A discussion list has the primary use of supporting a
discussion amoung many people.

A broadcast list should have From: set to the originator of the
message. If Reply-To: is present it should be the same as From:.

A discussion list should have From: set to the originator of the
message and the Reply-To: set to the email address to post messages
to the list.

The T13 list is certainly a discussion list but it seems to not have
a Reply-To: header line. The Reply-To: seems to have been removed
sometime in 2002.

But now we get to the hard part of this: So much email client
software is designed incorrectly, configured incorrectly or used
incorrectly. This makes any discussion of how a list should have
From: and Reply-To: set a worthless discussion. It should be noted
that a correctly operating email client *NEVER* uses the Sender:
header line and it *NEVER* uses the Return-Path: header line. When
replying to a message it *ALWAYS*, unless explictly overriden by user
action, uses the Reply-To:, if Reply-To: is present, for a "reply
message" else it uses the From: address.

A properly implemented email program will have options to display
and/or select the From: and Reply-To: at addresses at appropriate
times.

BTW: The T13 list is set up OK. It probably should have a Reply-To:
header set to the list's email address. It used to have that. But I
would bet it was removed because there are so many incorrect
inplemented/configured/operated email client programs out there in
the corporate world.
