After following the document "Corrections you need after upgrading Debian from version 12 to 13 (trixie)," I discovered that the used_quota table in the vmail database is not being updated when sending, receiving, or deleting emails.

I noticed that in the old configuration file, dovecot.conf, there's a dict entry that references quotadict = mysql:/etc/dovecot/dovecot-used-quota.conf, but this entry is missing from the new configuration file.
Any ideas about this?
