Here'e one for you....
Our web server has sendmail running on it. I have recently found that it is using our mail server as a relay host. What should I do to stop relaying in Sendmail?
Thanks!
If you are running RedHat, you should have a /etc/mail/access file. If you don't want any relaying, except for people logged into your machine, then this is all that should be in your access file:
localhost.localdomain RELAY localhost RELAY 127.0.0.1 RELAY
or something like this. If you have other lines in it, remove them, save the file, and run a 'make' in that directory. Then, restart your mail server:
service sendmail restart
That should do it.
