[Dovecot] Quota from passdb sql

Hello folks!

Is it possible to retrieve quota information from a passdb sql lookup and using static userdb?

I've tried here without success, and I can't find in the wiki or forum.

Some ways I configured dovecot-sql.conf:

1. password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS quota, password FROM users WHERE email = '%u'

2. password_query = SELECT email AS user, CONCAT('maildir:storage=',quota) AS userdb_quota, password FROM users WHERE email = '%u'

With userdb sql things worked perfect, but as I can use static userdb I just need quota information per user from passwd sql.

Thanks, Bruno.
