I am wondering if I need my own DNS in order to receive emails on my Ubuntu VPS? I am currently using name.com's DNS with my domain and pointing it with A records to my server, and that works for viewing my site but I can only send mail from the server from firstname.lastname@example.org. How can I receive mail from other people without setting up my own DNS?
Could I have an MX record (from name.com) pointing to my server? The point is, I don't want to have to set up my own DNS (like bind9 or anything).
