Let's assume I have a server set up with an email address like [email protected]. Now I have distributed my business card with the e-mail address to all people all over the world and they keep sending me confidential emails. But now I don't feel like paying for the domain mydomain.tld anymore.
But nowNow if someone buys the domain and creates a mx record pointing to the his own mail server he can read all my confidential emails the people are sending me right?
No, I can't tell them to stop sending confidential mails because I can't contact them.
Are there ways to prevent that or is the only option I have is to pay for the domain until I die?
