Look at the raw message or at least the raw message headers. You can do
this with, e.g., less or vi on the mailbox containing the message or
with any mail client that will show you the raw message or the complete
headers.

Here are the messages I received from you minus some headers such as
Received:, Delivered-To: and MailScanner headers added by MTAs in transit.

message sent by echo "test message 1" | mail -s 'test mail 1' -r mark@

test message 1
----------------------------------------------------------

Return-Path: is set by the final MTA to the envelope sender set by the
-r option. The message contains both Subject: from the -s option and To:
with the recipients address. The From: header is also set freom the -r
option


message sent by echo "test message 2" | mail -s 'test mail 2'

test message 2
----------------------------------------------------------

This message is the same except the From: and Return-Path: are the
user at host that sent it because there is no -r option.

And how did you look at it to determine that? The messages you sent to
me clearly do have appropriate To: and Subject: headers put there by
your mailx User-Agent:
