I have the test mail attached to this mail. There's something else strange:
X-Original-To: ankuendigun...@maennerchor-kirchseeon.de
Delivered-To: ankuendigun...@the-grue.de

Where does the "@the-grue.de" come from?



Postfix delivery.

This is the generated file /var/lib/mailman/data/virtual-mailman

...

# STANZA START: ankuendigungen
# CREATED: Thu Feb 18 14:28:43 2021
ankuendigun...@maennerchor-kirchseeon.de ankuendigungen



The above virtual mapping says deliver mail to
ankuendigun...@maennerchor-kirchseeon.de to the local address
ankuendigungen and postfix appends the local domain.


I see... I tried to fix that:

- rmlist ankuendigungen

- add VIRTUAL_MAILMAN_LOCAL_DOMAIN = 'maennerchor-kirchseeon.de' to mm_cfg.py

- newlist ankuendigungen
- restore settings with config_list

Now, virtual-mailman looks like this (just an extract):

--------------------------------------------------------------------------------
# STANZA START: ankuendigungen
# CREATED: Sun Mar  7 16:59:58 2021

ankuendigun...@maennerchor-kirchseeon.de ankuendigun...@maennerchor-kirchseeon.de ankuendigungen-ad...@maennerchor-kirchseeon.de ankuendigungen-ad...@maennerchor-kirchseeon.de

--------------------------------------------------------------------------------

I subscribed to the list, got the confirmation mail and replied to that. But now, the user is not known any more:


<ankuendigungen-requ...@maennerchor-kirchseeon.de>: user unknown

I didn't add that user, but I didn't have to add it when VIRTUAL_MAILMAN_LOCAL_DOMAIN wasn't set and it worked... What am I missing now?
