I host my own email. Incoming messages are sent directly to my SMTP server. Outgoing messages are sent through the ISP's SMTP server. (This service is included with the internet service from the ISP, so I do not need to register for this service separately.) The IP address rarely changes, but sometimes it does, and when it does change, I can update the DNS records.
