# ------------------------------------------------------------------------
# The FetchChunk method is deprecated:

# bundleObj is a CkEmailBundle
bundleObj = imap.FetchChunk(startSeqNum,count,failedSet,fetchedSet)
if (imap.LastMethodSuccess == False):
    print(imap.LastErrorText)
    sys.exit()

# ------------------------------------------------------------------------
# Do the equivalent using FetchRange.
# Your application creates a new, empty EmailBundle object which is passed 
# in the last argument and filled upon success.
