> What can you do?
Register your own domain and run your own SMTP server?
Better make sure you renew your domain each year, else...
--- You are no more.
Don't have $5 per month to lease a VPS and run your SMTP server?
--- You are no more.
Has your domain gotten on some mail blacklists?
--- You are not more.
Thinking somewhat along the same scale, I'm planning for having 2 years+ of domain name registration, Fastmail payment & (I should) have Thunderbird constantly syncing the full IMAP to the disk.
In the name of efficiency, it won't be the state doing it until someone, or groups of someone, get sufficiently pissed.
EDIT: passwords & other secrets must be shared with someone of trust.
