I was playing with password_query but not sure did I'm on right direction.

password_query = \
  SELECT username AS user, password, \
    '/var/spool/postmail/%d/%n' AS userdb_home, 1002 AS userdb_uid, 1001 AS
userdb_gid \
  FROM mailbox WHERE username = (SELECT goto FROM alias WHERE address =
'%u')

I'm using dovecot --version: 2.3.18 (9dd8408c18) and my configuration is:
