This is a provider for Dan Bernstein's `Maildir` mailbox format, used primarily by the qmail MTA, and also by some MUAs such as mutt.

Further information about the format of a Maildir mailbox is available here.

This provider supports the following properties:

Name | Type | Description
--- | --- | ---
mail.maildir.home | directory path | The path to a directory that holds Maildir mailboxes. Such files and directories will be exposed as mail folders by the provider.
mail.maildir.maildir | file path | The path to a Maildir directory which should be considered to be the primary inbox for the user (equivalent to the MAILDIR environment variable). Requests for "INBOX" will return this as a Folder. If not set, `${user.home}/Maildir` will be attempted.
