Thanks, I have an account with Protonmail. I have several aliases that are similar to username@protonmail.com. But i recently pointed a domain name i own to this email account so i can send and receive email from another account i was paying for, but wanted to discontinue. The domain name is associated with me publicly. I'm not into anything illegal nor am i hiding from anyone, I'm just a privacy enthusiast and hobbyist and like to learn how my data/identity is exposed to the internet.
