I run home mail sever for a while. I used to have smtp at home but a few years back I switched to a smtp proxy/forwarder on AWS ($5-6/month) connected via TLS SMTP on custom port at home (which also serves IMAPS on a custom port). Once a year I have to update DNS when my Comcast IP changes. Otherwise it is completely trouble free setup.
