We have a daily cron-job which checks the quota usage and informs
the user via mail if more than 85% is used. The scripts limits the  mails
send to each user to one every week. An other mail is send if 100%
usage is reached.

Two other ways i can think of is parsing cyrus logs, or using the  
notify daemon
