First debug is to assign the server.select_folder() return values, and 
subsequently print them for inspection. (know what you are dealing 
with/that you have been given something to work with)

The server.search() doesn't request ALL of the msgs. Are you sure those 
missing from the 'group' are not marked as 'read'? So, second debug 
would be to remove the 'UNSEEN' criteria and observe any difference.
