However venv/data/postfix_lmtp does not contain abuse@domain, so postfix rejects the mail.
acceptable_aliases is a Mailman 2 compatibility "feature". It may contain regular expressions, so in general it is not possible to update postfix_lmtp or postfix_domains to accept mail for those addresses.
As far as I know, you will need to update Postfix's routing (using virtual aliases, for example) to redirect those addresses to the appropriate Mailman list posting address, as well as adding them to the acceptable_aliases of any list that prohibits implicitly addressing the list.
