   There isn't a method defined in any RFC to do so, because there are a number   
   of hurdles that make it infeasible:   
      
   - *WHO* decides what groups to include on that list?   
   - How far back do you want to go/removed since *WHEN*?   
   - For each user, the server would need to remember the last time that user   
     checked the groups, and what groups have been removed since then. *WHERE*   
     does the server store this information?   
   - *WHY* would the server retain information it has already removed?   
      
   The *only* method to do this is using the "LIST" command.   
      
   Alternately, you could send the "CAPABILITIES" command and see what the   
   server returns. Maybe your chosen server has a method to do what you want.   
   (Don't count on it.)
