I am running a server with Fedora core 1, using sendmail-8.12.10-1.1.1. We added proxsmtp to one of our firewalls, so it intercepts mail before sending it on to the mail server. Unfortunately, the box is acting as a relay server now, even though it is set up properly. We are running a 192.168.0, class C internally. I have to add the network in /etc/mail/access, or users get relaying not allowed messages, but this allows the proxsmtp box to act as a relay. Is there to prevent this, but still allow local users to send mail through the server? Raymond
