title: Get Google Group member's email delivery status
body: <p>Within a group (using the web/gui), you can see 'bouncing', 'non-verified' etc. etc. next to a user.
  Is there a way to get this info via the API?</p>
  
  <p>Using python, I can use RetrieveAllMembers to ... retrieve all members.  The returned GroupMemberEntry objects don't have the 'status' (for lack of a better word) of the user.</p>
  
  <p>My goal is:
  1) Dump all groups in my domain 
  2) Check group for bouncing addresses
  3) Email group owner about the bad addresses/users.</p>
  
  <p>I can do #1 and #3.  It's #2 that I need help with.</p>
