S= is the "physical size", W= is the "virtual size". quota=count / vsize calculations should be using the W= value, not the S= value. > Even after deleting the list index (dovecot.list.index) as well as the > mailbox indexes, recalculating the vsize seems very quick so I feel like the > incorrect vsize is being fetched from a cache somewhere instead of being > recalculated..? The sizes can also be stored in dovecot-uidlist.
