Note the above says you are delivering directly to a local domain and
not via virtual_alias_maps. If this mail doesn't get processed by
Mailman, it is because you haven't started the Mailman service
(mailmanctl which in turn starts the qrunners)

This mail is originally to test at lists.example2.de and is mapped by
virtual_alias_maps to the local address 'test' to which Postfix
appends its cannonical hostname. Thus the mail is mapped to
test at example.org which is handled by the Dovecot LDA and not by
Postfix' local delivery, thus the 'test' alias in data/aliases is not

If you want to use the Dovecot LDA in this way, The easiest thing for
you to do is to not use Postfix virtual domains at all. Just add your
lists.examplen.org domains only to my_destination in main-cf and
remove the ,hash:/var/lib/mailman/data/virtual-mailman from
virtual_alias_maps. Then you can also remove
