integer. Examples of such resources are:

Name Interpretation

STORAGE Sum of messages' RFC822.SIZE, in units of 1024 octets

MESSAGE Number of messages

roots". Each quota root has zero or more resource limits. All

mailboxes that share the same named quota root share the resource

limits of the quota root.
