Hello, For my Postfix web server, I was able to get the example working that was at the bottom of the web page here: http://www.postfix.org/RESTRICTION_CLASS_README.html#external. In that section of the web page, it says "It is left as an exercise for the reader to change this into a scheme where only some users have permission to send mail to off-site destinations, and where most users are restricted." I've tried many many different things but have been unable to change the scheme where some users have permission to send mail offsite and most users are restricted. Can I get a little help with this? I'm guessing this is a small config change that I'm completely missing.
Thank you.
