Cyrus IMAP Server: Special Characters ************************************* This document is supposed to be a repository of "special characters" used in Cyrus naming of users, folders, directory paths, etc. Current Uses ============ Character: + * (LMTP) Separation of postuser and target mailbox for delivery * (LMTP) Separation of username and submailbox for delivery * (IMAP) Flag at end of login name that indicates that LIST should return LSUB results (when imapmagicplus is set) * (POP3) POP a subfolder directly (e.g. rjs3+foo POPs user.rjs3.foo) Character: . / * [mailbox names] Hierarchy separators Character: ^ * [mailbox names] In unixhierarchysep, ^ is the part of the internal name that represents a '.' Characters: @ % * [usernames] These are realm separators for the purposes of authentication Future Uses =========== Character: + * IMAP LIST filters (e.g. rjs3+foo will only list folders that match foo*) * possibly other interpretations here: - rjs3+foo will do an effective chroot(foo.) - rjs3+foo will only list folders in user.rjs3.foo*
