Rent a VPS outside your jurisdiction (crucial thing), preferrably in a country where not many know your native language, using fake address and name, use it as VPN peer or install your own mail server on it to avoid that crap.
To set up your own mailserver you will need to buy a domain name. Don't do it at all that shitty popular domain sellers like GoDaddy or Yahoo, choose some small company with payments in crypto and again out of your jurisdiction. Use fake address and name for registering domain, as with VPS. Nobody from small company abroad will check them.
Preferrable use of private VPN is not what you think or what all that motherfuckers who advertise their "Safe and Effective VPN" honeypots tell you. Set up a VPN server on your computer and setup VPN client on VPS to connect to it from outside. That kind of incoming connections are barely tracked. Three-letter agencies track your connections to outside, not outside connections to your computer. Redirect all your traffic to that tunnel established from outside. That will look for agencies or any other man-in-the-middle like somebody from other jurisdiction connected to your computer and you always could deny everything about it - "I know nothing, looks like somebody from abroad tried to hack me, it is a usual thing in Internet, so fuck off", not like you suspiciously initiating connection to some abroad service.
There are always exist a simple and easy way to fuck three-letter agencies without any consequences. All you need is just some brain and effort to read RTFM, nothing more.
