> 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.

can you explain your need clearly?

with the following:

smtpd_sender_restrictions =
     check_sender_access hash:/etc/postfix/access_sender

== access_sender
joe@example OK
jim@example.com OK
example.com reject_unauth_destination
.example.com reject_unauth_destination

joe and jim can send "offsite", while other *example.com can only send
to "managed" domains (mydestination, relay domains, virtual mailbox
domains, virtual alias domains).
