dovecot - Jul 2008 - fs quota check with server does not support, rquotad

I think the problem is in these few lines:
----------------------------

dovecot: Jul 15 18:13:21 Info: IMAP(01234567g): fs quota add storage dir 
= /home/h1/sc/01234567g/mail
dovecot: Jul 15 18:13:21 Info: IMAP(01234567g): fs quota block device = 
homesvr:/h1
dovecot: Jul 15 18:13:21 Info: IMAP(01234567g): fs quota mount point = /home/h1

----------------------------------

Since my configuration file only have

plugin {
quota  = fs:INBOX:mount=/var/mail
}

shouldn't /home/h1 be just ignored?
Or there are some parameters in "quota=" to ignore this mount point?
