create new maildir folders

mmkdir dir ...

mmkdir creates new maildir folders.

Parent directories are created as needed, and attempting to create an existing maildir is not an error.

New maildir folders are created with mode 0700, i.e. readable and writable by the owner only.

The mmkdir utility exits 0 on success, and >0 if an error occurs.


Using maildir format

mmkdir does not support maildir++, you need to transform nested maildir++ folder names yourself.
