Grr. Sorry, I pressed the wrong keys there. Abraham Ganem wrote: > 1. I have not been able to understan how to setup the DNS.

Is your computer supposed to serve DNS to other computers? In most universities, there will be a Computer Services department to look after those computers. (The name is different at different institutions). I'm guessing that you just want a personal computer. In which case, I'd get the IP addresses of the appropriate DNS servers from the Computer Services department, run system-network-config, and plug the details in there. For a dial-up computer, you'd get those details from your ISP. > 2.

Often that will specify the "From:" account. Otherwise, look at the myhostname and mydomain lines in /etc/postfix/main.cf.
