At NAT'ed sites it is probably best to deny Windows clients outbound
access on port 25. Users who are accessing external mail services can
change their MUA settings to use port 587 (submission), or you can make
per-user/destination exceptions in your NAT firewall.

Again as Simon says, this is not the best place to discuss this, as it
is only tangentially topical to Postfix. And please do not top-post
your replies. Thank you.
