I don't think I understand what you want to do. If you want the Mailman
list to 'advertise' itself as listname at MAIL.myserver.de, all you need to
do is change the list's host_name attribute on the General Options admin
page to mail.myserver.de if it isn't already.
If what you are asking is for Mailman to create virtual alias map
entries for Postfix of the form
listname at mail.myserver.de listname
You need to set
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['mail.myserver.de']
in mm_cfg.py instead of what you have, and then run Mailman's
bin/genaliases to generate Mailman's data/virtual-mailman* files with
the appropriate entries. You also need to reference this file in
This is what I tried to say below.
