Returned mail: User unknown Hi List;
I keep getting emails similar to the text below. I/We own the domain dataintellect.com and we have email addresses setup however I always see a bogus dataintellect.com email address as the sender.
-or is this simply a random spam email?
Thanks in advance for any advice...

I have to deal with this all the time. Some spammer or zombie is sending out emails from @yourdomain.com and there's not much you can do about it. You might consider adding SPF records to your DNS. If you have a catch-all address, you might consider temporarily disabling it. I also use milter-sender on my boxen which blocks a BUNCH of these.
