How to create email quotas for hosting account in dovecot?

Question

postfix

Now I have quotas for mailboxes, for example, the result of a query from the /etc/dovecot/dovecot-sql.conf.ext file will be like this:

+--------------------------------+--------------------------+-------------+--------------------+
| name                           | dns                      | pass        | userdb_quota_rule  |
+--------------------------------+--------------------------+-------------+--------------------+
| [email protected]                 | test.com                 | testpass    | *:bytes=5000000000 |
+--------------------------------+--------------------------+-------------+--------------------+

In my organization, there is a "profiles" table.
In the "dns" table I have the domains for these profiles.
In the "mails" table, I have email boxes for these domains.
My folder structure where this whole thing is stored looks like this:
/var/vmail/<name of domain>/<name of mailbox>/
I mean this structure

/var/vmail/<name of profile>/<name of domain>/<name of mailbox>/

Can I make a quota not for a domain, not for an e-mail box. How can I make a quota for the field "name of profile" ?
Can this be done with Dovecot or should I use disk quotas? What are the ideas?
