[Mailman-Users] mailman with postfix and virtual mailbox domains

[Gerd Moritz]

Hello,
I have a postfix server running which can handle mail for 3 domains
via "virtual mailbox domains".
Now I want to use mailman to offer mailinglists for those 3 domains.
I read the documentation and found
http://www.gnu.org/software/mailman/mailman-install/postfix-virtual.html
but this seems only be relevant for "virtual alias domains" which is
not what I am using.

How is mailman/posfix supposed to be configured for usage with
"virtual mailbox domains" ?

Thanks a lot and greetings,

Gerd Moritz
