# ------------------------------------------------------------------------
# The FetchHeaders method is deprecated:

# bundleObj is a CkEmailBundle
bundleObj = imap.FetchHeaders(mset)
if (imap.get_LastMethodSuccess() == False):
    print(imap.lastErrorText())
    sys.exit()

# ...

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