Hi all! Can anyone help me out with some Postfix problems. I'm setting up an email server using Postfix and the ipop3 program with Red Hat 9. I can send and receive mail on the local machine (to anywhere, from anywhere), and other users on the local network can use the SMTP to send to other users in the same domain. The problem is that other users on the local network CANNOT send mail to other domains.
In other words, how do I allow users on the local network to use my SMTP to send mail to other addresses outside of my server's domain while still not having my server act as an open relay? Background: I've already specified the following changes in the stock /etc/postfix/main.cf: mynetworks_style = subnet mydestination = $myhostname, localhost.$mydomain localhost $mydomain In /etc/postfix/master.cf I've only made this change: smtp inet n - n - - smtpd Other than that, the config files are plain old stock from Postfix 1.1.12-1. Any suggestions? We're using a GlobeDSL connection. Therefore, there's some NAT going on that maps the public IP to the private IP.
