Looks like the code explicitly ignores folders that start with a dot,
and forbids you from creating groups whose name starts with a dot.

I'm not a maildir expert, but it looks like the standard maildir format
doesn't provide for multiple folders, and the maildir++ format does
provide for multiple folders, but *requires* them to start with a dot.

Dovecot (the only program I know well that deal with maildir) uses
maildir++ by default, but allows you to turn on a setting that uses
non-dot-prefixed, potentially nested folder names.

But beyond that it looks like the "normal" thing to do is dot-prefixed
folder names (and subfolders emulated with multiple dots).

Does anyone know why nnmaildir does it the way it does? I suppose it
might make sense to give nnmaildir servers the option to choose between
"traditional layout" and "filesystem layout".
