[Dovecot] Convert to DBox

[Jeff Grossman]

I am thinking of trying out dbox format.  I am currently using maildir.  
Is it possible for me to switch just one user account to dbox while 
keeping all of my other users on maildir?  If so, how would I go about 
doing that?

Here is a copy of my dovecot -n:
