Quotas are stored in plain text files in /var/imap/quota.
Directory is hashed by user's login first character ( 'q' if it's
not in 'a'-'z' range ).
Filename is user's mailbox name ( eg. 'user.<login>' ).
First line is current usage in bytes 
Second line is user's quota in kilobytes.


mail1# pwd
mail1# cat m/user.mjawimap

mjawimap user has 1GB quota and uses about 825MB out of it 
( 84% usage ).

Bottomline is you can play with these files without any restrictions. 
You can change it, generate manually or from robot and it will all
be seen properly by cyrus.

Mentioned everyday quota warning checker can be a simple oneliner
