The only issue hosting your own non-bisiness mail server is that a lot of internet providers block incoming port 25, so you may not be able to recieve incoming mail.
Getting a reverse DNS setup may be an issue as well which will bring your mail score down.... But you can increase the score with SPF and DKIM implementation.
Just make sure that you secure your server from unauthorized relay or you'll be blacklisted in no time.
