Thanks very much Jim,
yes, the MLM's developer (Mailgust) indeed knows about the issue and the need for better handling of bounces; I'm assuming the problem doesn't exist when using smtp because the mlm has been coded suitably.
The mlm is still under development (Mailgust) so whilst waiting for more development (!) I'm fishing around for a fix ...
In the meantime I've contacted my hosting support to see if they can help at all.
Presumably of course, if my account is subject to a certain smtp restriction then i also shouldn't be able to use sendmail directly to get round this, but this 'bounce error' problem is the only apparent hurdle in the way.

Trouble is, when people mail the list they get a 'personal' mail delivery error from the mail daemon if there happen to be any dead or over quota addresses on the list at that time. Using smtp (on smaller lists) seems not to do this.
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.
So, is there a specific request I can send to the hosting support to get these mail delivery errors specifically directed to an admin address? ie, 'if a delivery error is generated when someone has originally mailed to xyzlist then forward to [EMAIL PROTECTED] rather than the original sender' ....
Here's a sampling of the headers this list, list-managers, emits:
From [EMAIL PROTECTED] Thu Nov 4 10:00:21 2004 Return-Path: <[EMAIL PROTECTED]> X-Original-To: [EMAIL PROTECTED] Message-ID: <[EMAIL PROTECTED]> Date: Thu, 04 Nov 2004 17:53:11 +0000 From: lee <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: mailing with sendmail binary / errors Sender: [EMAIL PROTECTED]
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'm asking here before contacting the host in case any of you have tried this before and found it definitely is / is not possible to set up.
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.
