I've just configured postfix using virtual domains (using dovecote) and therefore needed to alter the mailman-configuration. I decided to use lists.* to allow postfix to distiguish between mails that need to go to dovecote and others that are handled by mailman. Therefore I created a transport_map (lists.(domainname) mailman:) and registered mailman in master.cf using this configuration:
mailman unix – n n – – pipe
flags=FR user=mailman:mailman
argv=/var/mailman/postfix-to-mailman.py ${nexthop} ${user}
Also I added lists.(domainname) to the relay domains. According to the information given in https://www.gurulabs.com/downloads/postfix-to-mailman-2.1.py (section INSTALLATION) I now do not need to configure any aliases at all. But without adding the output from genaliases to /etc/aliases and afterwards running the newaliases command the mails are rejected (user not found in local alias map). Does anyone know why that happens?
My main.cf looks like that:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name.

First of all, do NOT list list.mathishoffmann.de in mydestination - it belongs in relay_domains only (see the ADDRESS_CLASSES readme). Oh, and like yoonix said, I don't see you defining any relay_domains at all.
Furthermore, you need to tell Postfix about valid recipients, with something like relay_recipient_maps = hash:/var/lib/mailman/data/virtual-mailman.
And finally, tell mailman that it can skip alias generation (MTA = None) and that lists.mathishoffmann.de is indeed it's primary domain (POSTFIX_STYLE_VIRTUAL_DOMAINS = ['lists.mathishoffmann.de']).
