If you host your own email, you may need to know more and do more than you think you need to do. I tried it for awhile, it was easy to set up with postfix. The problem I ran into is that large services like gmail and linked in would not send to me. They weren't rejecting mail from me; they wouldn't send to me. I think because I didn't do enough with <vague> reputation mechanisms </vague>, but I never really knew because I realized I wanted to receive mail now, not when I eventually worked it out. That's just one surprising (to me) example. Mail has a reputation for being easy to get started and hard to get right. I think that's a deserved reputation. I forward my domain's email to fastmail.fm, a paid service. I'm happy with it. Good luck.
