I've hosted my own email for over 30 years. I've watched it slowly change from a (somewhat) trusted environment into a war zone. Administration time went from nearly nothing to several hours per day up until about five years ago. For the past five years I've been using mail-in-a-box. (http://mailinabox.email http://mailinabox.email) It is generally problem-free, but problems can arise if you host it on a sub-par provider (or provider network). I highly recommend it!
