Comment 1 Jan Kundrát 2016-02-01 23:45:28 UTC 
Unfortunately, this is a bug in the IMAP server (which is reported as Openwave Messaging, Email Mx, version M.9.00.021.00 201-2473-182).

The IMAP server violates formal protocol syntax of the IMAP protocol by sending the mailbox name through the "atom" production even though it contains a space. Such names must be transmitted either via the "quoted" or through the "literal" productions -- see https://tools.ietf.org/html/rfc3501#section-9 for details.

Could you please file a ticket at your IMAP server vendor with a reference to this bugreport?
