This is a SELECT extension, which still includes having to use the IMAP 
protocol to obtain a list of folders, iterate over them to retrieve 
annotations, etc.

QRESYNC is very useful, most certainly, and potentially gives applications 
("clients" in this case) great performance boosts.

In fact, come to think of it, QRESYNC could be a KEP in and by itself, if not 
even just 'informational'. I would definitely be interested in pursuing 
implementation throughout various Kolab smart clients.

Kind regards,
