I already setup my own email server NDR 5.1.x messages to send back a response with my LNURL / BTC addreess for a specific amount of sats to be able to accept their spam emails.
Once they pay, their domain/server will be whitelisted. If not, emails are just rejected.

I want to see an email server where the spam filter is replaced with the requirement to pay 1 sat to each of the receiving addresses.

I hope this could make email decentralized again.
