So you host your own email server?
Discussion
At the very least, keep your email provider in your own country.
Those doing the surveillance want an identity touch point, and if you host your email service then it can be gotten from your domain registration (even if it is hidden, there is a fiat transaction to buy it).
A workaround is to buy a domain with bitcoin from njal.la .
Many do but email is doomed anyway as the other end of every communication is usually gmail.
