Just to be clear about the terminology:
- Quota is limit on the resources a user (or more precise  a folder /  
subfolder)
   can use.

   In older versions of cyrus and in most installations i know of the  
STORAGE resource
   is used. This is the sum of the size of all mail.

- The partition utilization is related to the  number and size of  
mails in a "partition" but
   cyrus does store additional metadata, uses hardlinks for copies of  
the same mail, can
   keep deleted mails/folders for some time

   You can use metadata partition and archive partitions to distribute  
the data to different
   partitions and use different types of disks to get the most usage  
out of faster (more expensive)
   disks. The mails/data moved to the archive/metadata partition will  
reduce utilization of the
   partition.


I can see a use case for a new extra resource types for mails on the  
archive partition and main
partition but this has available in cyrus at the moment
