I have been trying in the past to do this myself but I stopped for the following reasons:
what happens if your internet connection is lost while someone sends you an email? It probably will not reach your mailbox. If you host it on a private internet connection, it might drop now and then (ISP updates your modem at night, you need to turn off the electricity, etc)
its complicated.
mail is crucial for me. It needs to be 100% reliable.
I ended up buying a domain name and hooking it up to a premium email service (fastmail, but there are plenty others).
