I'm trying to configure an Ubuntu 11.04 box to send mail only, and not receive mail. I am fairly confused at this point. I know I need to install an MTA on the server like sendmail, postfix, or exim, but I get hung up when trying to configure them.
This is a web server, and I simply want it to be able to send mail.
Let's say the domain name is example.com. I have the email hosted with Google mail, but need this server that hosts my website to be able to send out email to both other users and email accounts like email@example.com.
Also, let's say that the hostname of my server is 'greatserver'.
So here are some questions: 1. Exim asks me for my FQDN. If I read about this correctly, this is basically an address that is reachable by anyone in the internet? Should this just be "example.com"? 2. Exim asks for a semicolon-separated list of recipient domains for which this machine should consider itself the final destination. I'm not sure what to put here at all. Do I need anything other than "localhost" and "example.com"? 3. Is it correct that the hostname of my server is just a single word, or more correctly, not a domain name?
