Perhaps you missed the point where the original problem was with an email 
address:

" I have this very odd email address found with one of our employees....
<hidden_user@172.17.0.1>"

Email addresses, in fact everything in rfc822 headers, are unrelated to 
tcp connectivity issues.  If the employee got the email I'm willing to 
assume there was connectivity.  If you wish, I can describe exactly how 
such an address could be in the rfc822 From header of a message that could 
be delivered to you - even if 172.17.0.1 is the address of the originating 
device and you have no way of reaching that address.
