if filesystem-quota for the user is present and another quota is
configured in dovecot, dovecot can not overrun the system-quota.
fs-quota not only reports used space, but also enforces the quota-rules
- regardless of dovecot configuration.
I would not recommend using filesystem-quotas as dovecot runs into
issues regarding indexes (see http://wiki.dovecot.org/Quota/FS for
Use maildir-quota, perhabs with dict-quota-storage, and no
filesystem-quota - this works great and also gives easy access for
generating reports about user activities through sql-queries.
