IMAP allows ranges like 500:*. However, the documentation says IMAPClient takes either an integer or a list of integers for a message or UID sequence. Is there a way to achieve selections list 500:*? Can an xrange object serve as a selection list? Thanks. Ross Boylan

String arguments like '500:*' are permissible, either as a single argument or an element of a list. xrange objects are not allowed. def messages_to_str(messages): """Convert a sequence of messages ids or a single integer message id into an id list string for use with IMAP commands """ if isinstance(messages, (str, int, long)): messages = (messages,) elif not isinstance(messages, (tuple, list)): raise ValueError('invalid message list: %r' % messages) return ','.join([str(m) for m in messages])

I've been overseas (getting married) and have had intermittent access to email. I'm glad you managed to figure this out. Message ids can indeed be passed as strings, ints, longs or tuples/lists of ints/longs. I'm adding a ticket now to make this clearer in the documentation. Regards, Menno
