c220854499511d9508aa416295e3da1fe1568bfaTimo Sirainen# Quota limits are set using "quota_rule" parameters. To get per-user quota
c220854499511d9508aa416295e3da1fe1568bfaTimo Sirainen# limits, you can set/override them by returning "quota_rule" extra field
c220854499511d9508aa416295e3da1fe1568bfaTimo Sirainen# from userdb. It's also possible to give mailbox-specific limits, for example
c220854499511d9508aa416295e3da1fe1568bfaTimo Sirainen# to give additional 100 MB when saving to Trash:
