I went ahead and just prevented groups from being returned, period.  
All of the options to try to work around the protocol are just too  
risky - it's very likely that a user would think an email was sent to  
dozens of people in a distribution list when in reality it was only  
sent to the first person in the list with the rest silently ignored.
