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 protected].
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?
