 /** Experimental driver for IMAP created just for fun. Features:
 * - list mailboxes with number of messages (Rows) and unread messages (Data Free)
+* - creating and dropping mailboxes work, truncate does expunge on all mailboxes
 * - list messages in each mailbox - limit and offset works but there's no search and order
 * - for each message, there's subject, from, to, date and some flags
 * - editing the message shows some other information
