It is. I'm using custom domains, but my username email is private and NEVER used or known.

This feels like an architectural flaw to me. If it's supposed to be private, then why is it available to send to on the public Internet, in a way that you are now therefore sensitive about?

That's the whole issue.. I don't use that email address for email, and I don't want it leaked.
