DSN and mailgroup

Correct. This is what distinguishes a mailing group from a mailing list.

Yep expected behaviour.

I would advise that for the vast majority of cases, this is not a good idea. Ideally you should be sending the email to somebody who can do something about it (list maintainer/owner).

For example if "I" as a third party send an email to a mailing list which I have no idea who maintains, or how to get it fixed, what use is it to send me a bounce email if one of the mailing list recipients didn't get a copy? There is little I can do about it and it also exposes a member of the list (who you may want to keep hidden for some reason).

You can set who receives the bounce using the mgrperrorsto: attribute. This must resolve to a single email address (as the return-path: can only be a single address). e.g.

mgrperrorsto: list-owner@organisation.com

To get the 'old' iMS5.2 behaviour of bouncing back to the sender (which as I said earlier, is not advised), you can use the '/' address. (note: I know this works in the new 2006Q4 version, not sure whether it was back-ported to 2005Q4, so results may vary).

e.g.

mgrperrorsto: /

Users can be fun that way.

That is pretty much what I suspected. I just had a quick look at the feature list and the "/" parameter was indeed added to messaging server 6.3 (2006Q4)

You can't. They aren't available yet. We are hoping to release the full version of 2006Q4 in the march 2007 time frame. Patches for upgrade from 2005Q4 are released after this time.

At this point, a waste of time. They won't be able to tell you anything that I haven't already told you.

So you choices at this point are:

1. Go with the more appropriate mgrperrorsto: set to a postmaster/mailing list maintainer address.

2. Wait for 6.3 to come out and upgrade to that.

3. Tell users that you are going to go with (1) until (2) then change the mgrperrorsto: parameters across to "/".

Shane.
