Probably simple relay problem

Hi,

I am having what I imagine is a really simple problem configuring
postfix to relay mail. I am trying to set up a postfix server that
will relay mail (newsletters) for a webapp. The relay server is
running on a different server than the webapp. So, it needs to
accept connections from the local subnet (or specific addresses,
whichever is easier to setup). I am using version 2.0.10 (what ships
with OS X 10.4).

In main.cf, I set:

mynetworks_style = subnet
smtpd_client_restrictions = permit_mynetworks, reject

With the above setup, postfix is still letting anyone on the internet
connect. I am not sure it is relevant, but the master.cf line for
smtpd is:

2525 inet n - n - - smtpd

Any ideas on what I am missing?
