The author of Postfix is also the author of TCP wrapper. I would say it
supports it.

However, you are much better served by using the internal Postfix
restriction support. You will find that since Postfix does not M4
line-noise for its configuration file, everything will fall into place
easily. More than 10 lines or so in your main.cf is an over-configured
Postfix setup ;)

mynetworks = 192.168.0.0/24, 127.0.0.0/8, EXTERNAL_IP
  -- Allows my private class C, my loopback, and the external IP of the
server.

Add in some SMTP auth, shake, and enjoy a smooth dose of good SMTP
