Thanks for your help, right now we use sasl auth and Works very good.
If the setup for example a gmail account and the change the gmail
address for some user on the postfix domain, postfix delivers that email.
I don't want to accept emails from our domain in our server if they
don't belong to my networks or they are authenticated.
For example if you setup you outlook to send an email from
u...@domain.com <mailto:u...@domain.com> using gmail as smtp relay, I
want my postfix to drop that email because it is coming from other
smtp server.
I hope this example helps.
I already answered your question. reread my post and go at the end
