I have plenty of server storage. Can mx route be used almost like a mail proxy? Mail stored locally and mx route used for just receiving and sending? Needs to be spouse friendly as well. Or if anyone else can recommend something else that fits that bill more.

Yep same DDClient is super simple to setup with name cheap. Followed ip address changes with very little if any down time. I’ve never noticed between ip changes.

I mean it is open source and you can go with something like lineage or graphineos to get around those things
