I have an email gateway that is running sasl and what I want to do is to configure is so that once users are authticated it will allow them to send email, through this gateway.
 
The problem is that when are authenticated and then email is that sent all the email is sent to another gateway but I want to change that so that it goes directly out, but I can not determine where to change that.
 
My MTA is postfix
