On Fedora and Centos, I'm seeing the socket being created as rwxr-x--- (0750).
To use it with postfix as a member in the defang group, it should be created as
0660 instead.
I wasn't sure about all the places that make_listening_socket()... it might be
called in a couple of places where changing the modes isn't appropriate.
