Looking good. But try:

$mydomain is in mydestination, is that correct?
BTW, if you have local commented out in master.cf, no local delivery
Did you read http://www.postfix.org/faq.html#firewall ?

You never check for relaying. That's not good. Or I didn't understand

Your master.cf looks like a SuSE version...
As a firewall mailer, EVERY part of Postfix can run chrooted (since you
don't need the local daemon). Get the source, and run
examples/chroot-setup/LINUX2 and change master.cf to run any daemon
(except for local, which doesn't run at all) chrooted.
