++++ Listing folders
All foldernames are presented between brackets like [X] where X is the foldername.
When a foldername contains non-ASCII characters it is presented in the form
[X] = [Y] where
X is the imap foldername you have to use in command line options and
Y is the utf8 output just printed for convenience, to recognize it.

Host1: folders list (first the raw imap format then the [X] = [Y]):
* LIST (\HasNoChildren) "." Trash
* LIST (\HasNoChildren) "." Drafts
* LIST (\HasNoChildren) "." Sent
* LIST (\HasNoChildren) "." Junk
* LIST (\HasNoChildren) "." INBOX

You can remove foldersizes listings by using "--nofoldersizes" and "--nofoldersizesatend"
but then you will also lose the ETA (Estimation Time of Arrival) given after each message copy.
