I've got a bunch of mail lists on a server which are all announcement only lists. On all of these lists the "From:" address is like how it is on the mailman-users list. It'll show up like: mailman-users-bounces+danb@zu.com@python.org on behalf of "Some User [su@wackedout.net]"

Now I know everything from "on behalf of..." onward is due to my mail client and not the list.

That is not actually correct. The part that Microsoft Outlook (and possibly other MUAs, but Outlook is the main one) adds is the part after From: through 'on behalf of'. Most MUA's just show

From: Some User <su@wackedout.net>

I would like the emails to be showing as coming from either just:

eg. mailman-users@python.org on behalf of "Some User [su@wackedout.net]" or eg. mailman-users-bounces@python.org on behalf of "Some User [su@wackedout.net]"

Now while there is the "anonymous_list" option, this looks as though it will remove everything so it would just show up as:

eg. mailman-users@python.org

Actually, I thing that making the list anonymous won't help you at all. It will make the From header be, e.g.

From: Mailman mailing list management users <mailman-users@python.org>

(the text part is the list's 'description') instead of

From: Mark Sapiro <mark@msapiro.net>,

but the Sender will still be, e.g., mailman-users-bounces+dan=zu.com@python.org

I'm unsure what to call this and the personalization options don't seem to be what I want either but I am playing around with a test list to figure out what option is the correct one to do this.

The "+recipient=example.com" part of the Sender: is a VERP like sender. In order to remove it, you need to remove whatever mm_cfg.py options you have set in mm_cfg.py (assuming this is your Mailman installation) that are causing it to be added. These are things like:

VERP_PERSONALIZED_DELIVERIES = Yes (default = No), and VERP_DELIVERY_INTERVAL = 1 (default = 0)
