The systems send hundreds of emails, every day, addressed to various folks at
their real corporate addresses, or to a few people out on the Internet, so it’s
not *any* kind of email that gets thrown out.

We only throw out email that is addressed to an account in our fake domain.
That domain has no valid recipients in it. I’m aware of what the email is, and
have determined that it’s not worth my time to deal with. It’s been going away,
by attrition, as we eliminate our legacy, on-prem systems, in our march to the
cloud, where we do things better.
