lock() unlock() Maildir mailboxes do not support (or require) locking, so these methods do nothing.

list_folders() Return a list of the names of all folders.

get_folder(folder) Return a Maildir instance representing the folder whose name is folder. A NoSuchMailboxError exception is raised if the folder does not exist.

get_file(key) Depending upon the host platform, it may not be possible to modify or remove the underlying message while the returned file remains open.

add_folder(folder) Create a folder whose name is folder and return a Maildir instance representing it.

add(message) __setitem__(key, message) update(arg) Warning These methods generate unique file names based upon the current process ID. When using multiple threads, undetected name clashes may occur and cause corruption of the mailbox unless threads are coordinated to avoid using these methods to manipulate the same mailbox simultaneously.

It is for historical reasons that dirname is named as such rather tha
