It's something I've tested in the past (few years back) by telneting to my
own SMTP server and submitting messages directly to the server to see how it
reacted under various circumstances.

Since you challenged the statement, I just tried duplicating this
behavior again, and found that sendmail is replacing the return path
header given in the SMTP message body DATA with the envelope sender data.
So somewhere along the line that behavior changed. I stand corrected.

Interesting...
