This is a convention used by IMAP clients, and defined by the specification, for defining folder names with Unicode characters. "&" is normally followed by a base64-type bastardization that encodes Unicode characters. "&-" is used to escape the special meaning of the ampersand, to specify a literal ampersand that belongs in the folder's name. It's the client that modifies the folder name and sends &- to the server. The server may, but is not required, to validate folder names. Unless you want to use Unicode characters in folder names, &- is all you have to worry about.
