Hi,
I currently have 1 mail server, which serves our school's internet and mail needs. It runs Redhat enterprise 2.4.9-13. On it is running exim 3.34. Currently we run novell on our main servers, but I am setiing up a test server running linux. To test the full functionallity of Linux, I have set up a second domain name for our email. So the problem is, I need to set up exim to serve both domains. The first which is already set up is wpps.wcape.school.za, and the second one which I need to set up, to go to a diffrent IP address to the first is wpps1.wcape.school.za. How does one do this? I have included my config file.
Thanks
Paul
p.s. I had to take the first couple of comments out, because i could not paste it all in, (microsoft products!!)
