To send e-mail to ThisIdiot@andycanfield.com you have to send it to ThatIdiot@yandex.com. There is no e-mail service at andycanfield.com because all of the worlds SMTP servers are interconnected by mandatory certification.
There there is no e-mail server on my web site. Your e-mail client connects to SMTP.alpha.com and it talks to SMTP.beta.com which talks to SMTP.gamma.com on down the line until the message gets to SMTP.target.com and delivers the message where he can pick up the message from POP3.target.com. All the world's SMTP servers are inconnected by a web of paid-for certificates. Unlike HTTPS, there is no human involved, so nobody can say "Yes, go ahead and accept that certificate". Your certificate is either signed by a recognized organisation, or you're out of the chain.
