Normally for Mailman/Postfix integration, Mailman is configured with
--with-mail-gid=mailman and data/aliases.db is owned by
mailman:mailman. The owner of data/aliases is not important, but the
group should be 'mailman'.

Are you sure you mean 'aliases'? Normally, only the ownership of
aliases.db is significant. See the DELIVERY RIGHTS section in 'man 8
