http://www.postfix.org/documentation.html indexes a lot of good stuff, and you're probably specifically interested in "Relay/access control overview", Not an open relay.
with "Address verification" Looks interesting and may be more to what I am looking for but not fool
I guess you have not read the rest of the thread yet. proof.
and "Stopping backscatter mail" being handy reads if you're feeling a tad more aggressive. Using the address verification stuff has worked out well for me over the last 6 months or so since I implemented it - both internally as a way to save some bandwidth / queue processing time on my backup mail server (it verifies recipient addresses on the main MX before accepting messages), and as externally as a way to reject those made-up hotmail/yahoo addresses (verify the sender's address validity before accepting the message).
