I run pfsense with dyndns and a short TTL. It updates my DNS provider instantly when the gateway IP changes. For mail I got a cheap vps running pfsense again, tunneling back home via Wireguard and haproxy to link up connections. It is very stable and not as hard to set up as it sounds (and cheap).

In the meantime
