Others here can probably quote the RFCs on this better than me, but I'll
offer my limited opinion. First, those errors you mention should never
go to the message author, but should instead go to the envelope sender,
or return-path, which should be the MLM. I don't know if this is a
sendmail/smtp issue or just an issue with your MLM. Then again, there
are plenty of sites that misdirect DSNs even with the MLM set up right.

Here's a sampling of the headers this list, list-managers, emits:
From list-managers-owner@greatcircle.com Thu Nov 4 10:00:21 2004
Return-Path: <list-managers-owner@greatcircle.com>
X-Original-To: list-managers@greatcircle.com
Message-ID: <418A6C87.2070600@btinternet.com>
Date: Thu, 04 Nov 2004 17:53:11 +0000
From: lee <davislee@btinternet.com>
To: list-managers@greatcircle.com
Subject: mailing with sendmail binary / errors
Sender: list-managers-owner@greatcircle.com
A site would have to be really misconfigured to send DSNs to the From:
address with all that info at hand. You might check to see what your
current MLM is sending in the way of headers.

I've never tried rolling my own MLM, but have used Majordomo, ListServe,
and for the last ten years or so, SmartList. They've all been hosted
by my ISP, so I haven't personally configured this aspect of a MLM;
SmartList uses something called "flist" to deliver the mail; it may
go through sendmail on its way, but I don't know, and I don't think
that's relevant to your question.
The ultimate answer to your last question is: yes, it is definitely
possible to set up a MLM to encourage DSNs to go to the MLM, not the
message author.
