Fair enough, but unlike maildir, it does not require the mailbox owner
to have a unix account.  So like maildir, but provided as a service
without prividlege.

But that said, it's still very unixy.  There's no "export mail" function
because you don't need one.  In a multidomain setup, your path is
/<pathtocyrus>/data/<domain>/user/<username>/<folder>/<number of item>. 
The database files can be separated into the same tree structure
(replace data with meta) s.t. you can divide the disk access between
index functions and data retrieval functions.

I've been using cyrus for about 20 years now.  When I started, dovecot
either didn't exist, or somehow bit my ass.  The ability of cyrus to
cluster and scale is well documented.  Support for things like NFS and
federations is mature.

Anyways... just don't store your email data in relational DBs.  Waste of
effort.
