I'm likewise curious - a family member runs a mail service on a box in his basement for everyone with a @lastname.com with about 40 or 50 inboxes. He's indicated he'd like to pass that responsibility on as he's nearing 75 years old and the everchanging spam and delivery rules make it tedious to keep up, but I have very little interest in running a mail server myself. Would love to find somewhere for super low volume mail under $100 or $150/month that could keep that domain intact..
