Ahhh. I see. That is neat - save populating the main Maildir
with files.

Just one other quick question:

How does the flat file for authentication scale to large numbers of
accounts? Eg:

auth_passdb = passwd-file /path/to/file

Courier makes a db version of the userdb file for fast access.
Is this needed/planned for Dovecot? How does it scale for
tens of thousands of users?
