Yes, that's what I meant. Sorry.

All of these would depend on Postfix. If you set

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'lists'

you will get virtual maps like

listname at example.com  listname at lists

and if you set

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'lists.example.com'

you will get virtual maps like

listname at example.com  listname at lists.example.com

and if you set

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'i_dont_know_what_im_doing'

you will get virtual maps like

listname at example.com  listname at i_dont_know_what_im_doing

I would hope that that would be clear from the comment added to
Defaults.py(.in). I'll add a bit more to try to clarify it.

Probably. What I think you want is

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'lists.example.com'

plus whatever is necessary in Postfix to ensure that Postfix treats
lists.example.com as a local domain, i.e. it must directly or
indirectly be in mydestination.

If you were to put

VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'lists'

in mm_cfg.py, I'm gussing that Postfix would append mydomain and try to
deliver to listname at lists.smtp.example.com in your case which would
probably fail, unless you also added lists to mydestination in which
case, Postfix might be able to deliver to listname at lists and would
identify it as such in logs and Received: headers.
