Gets a list of the folders on the server using imap_list.
The host information is automatically indexed in the $mailboxInfo property as $mailboxInfo["host"] if a URI abstraction was used to make a connection. The $pattern argument can be used to search for specific mailboxes, see imap_list for possible syntax. All folders on the server are returned by default.
If the $rtn argument is FALSE, the information retrieved from imap_list is merged into the $mailboxInfo property.
