If you have an email address and it says Marsha@whatever.com, and I go to a site like Ashley Madison, and signup and use a fake address like news@whatever.com, I will still receive all mail with that address into my marsha@whatever.com, if it’s set up as a “catch all.”
It doesn’t matter what is in front of the @ sign, if you’ve got the main email setup as a catch all. I might be wrong, but I don’t think so.
I do not disagree
