Whoa, are you sure about that? I don't think this is correct. Seems to
me that the smtp daemon writes the header. Maybe there are some cases
where the client supplies one... but I don't think you can flat out say
it's not the MTA.
Here's a snippet from the qmail-local man page:
The message's envelope sender is sender. qmail-local
records sender in a new Return-Path header field.
Now I know that's not the MTA but rather the MDA. But that does go to
show that it's not solely the client that can be responsible for the
Return-Path line. Also, I know this for a fact: when I use the qmail
"sendmail" binary to send mail from pine, it writes my local user
account's name into the Return-Path header. I had to set pine to deliver
via smtp to the local qmail-smtpd in order to force it to accept the
client-supplied "From" address as the Return-Path.

Agreed. ;)

More specifically, it is probably tcpserver (or whatever superserver he's
running) that is causing the ident requests.
