Maybe not, but for your needs wouldn't nested dicts do the trick? Or nested 
objects?

  class MaildirInfo(object):
    def __init__(self, path):
      self.path = path
      self.subdirs = [] # array of more Maildirinfo instances
      self.other stuff here as needed ...

  top = MaildirInfo("top-maildir-path")

then do the os.walk thing and fill out the data structure.

.subdirs could also be a dict mapping named to MaildirInfo instance, depending 
on your needs.

Rather than Alan's take that nobody would want to do this, as someone who has 
spent much time mucking with my mail tree using many scripts I'd say: everyone 
wants to do something different. The task itself is fairly simple, so roll your 
own. That makes is easy to implement your own policy instead of trying to do 
some kind of feature survey of stuff out there.
