I recently got a VPS and is in the process of making it into a web server. I got everything setup but mail. I've been working on this mail server for a bit, but I haven't had much time to work on it. When I do though, I try to use a tutorial. But each one has seem to have caused an issue so I would wipe the server and start over. Recently, I was following this tutorial and it seemed promising, but then when I tried to send mail it would just freeze up and I would have to stop and start apache. My knowledge of linux is very limited, but I'm trying to learn. So far linux has been good, and I really like it, but mail has been the last thing that has stopped me. I'm currently running Ubuntu 10.04 x64.
Is there a tutorial that you would recommend for Ubuntu 10.04?
