I've noticed that if a user's maildir gets created by deliver or
pop/imap without the convert plugin running, the maildir structure is
fine (no maildirfolder file). But, if a user gets converted, there is a
maildirfolder file in the user's base maildir directory. As far as I can
tell, that doesn't cause any problems, but I just wanted to mention it.
I've looked at the code for a while but didn't find why it behaves
differently.
