Interesting find! Out of curiosity, what was the content of the emails you sent and how exactly did they bring you to uncover these workstation names?

Just a dummy e-mail. You'll get back either an error response or the IP address of the machine.

I'm guessing empty message, check for error status later. Just send a bunch of emails, see which hostnames resolve (vs not).
