Mailman 3 core is still in beta. Mailman 3 web UI (Postorius) is still
in alpha. You shouild probably be installing Mailman 2.1./15 or the head
of the 2.1 branch at
<https://code.launchpad.net/~mailman-coders/mailman/2.1>

And Mailman 2.1 is a lot different from Mailman 3.

Mailman 3 does not do delivery to a Mailman wrapper via aliases like
Mailman 2.1 does. It is designed to use LMTP to deliver from Postfix to
Mailman.

Remove Mailman 3; install Mailman 2.1.15 or later, and come back if you
still have trouble.
