[Dovecot] warning regarding quota and mboxes

[Chris Young]

if you're getting errors, then quotas are probably not working.

as timo suggested,
maildir only works with maildir
but your mail location shows MBox and Maildir formats
use Dict quota as it works with both MBox and Maildir

I don't know enough about dovecot to know why you'd have two formats, MBox
and Maildir, defined for mail_location.

And it seems odd that your mail_home is under /var/spool. I was under the
impression that /var/spool was for temporary data. Are you actually keeping
mailboxes there?
