puts all the configuration in a single directory, available to the container as a volume;
puts the postfix spool in a separate directory.
As a side effect, various bugs are fixed: in particular, modifying host-side a file that is mounted individually in the container behaves in unexpected ways (if the modification is done atomically, the write is not visible to the container until it is restarted...). This occurs when using Ansible or when using an editor host-side.
