[Dovecot] Quota + MySQL

[Matt Rude]

Hello, Im having problems getting Dovecot to read the quota info from 
MySQL.  My current dovecot.conf file is below.

If I run the user_query of:

user_query = SELECT 1000 AS uid, 1000 AS gid, maildir AS home FROM 
mailbox WHERE username = '%u' AND active = '1'

Everything works fine but if I run the user_query of:

user_query = SELECT 1000 AS uid, 1000 AS gid, maildir AS home, 
concat('quota=maildir:storage=', floor( mailbox.quota / 1024 )) AS quota 
FROM mailbox WHERE username = '$u' AND active = '1'

if I were to run the query from MySQL the I get:

+------+------+----------------------------------+------------------------------+
| uid  | gid  | home                             | quota 
         |
+------+------+----------------------------------+------------------------------+
| 1000 | 1000 | mattrude.com/lists at mattrude.com/ | 
quota=maildir:storage=512000 |
+------+------+----------------------------------+------------------------------+

If I run the above query I am unable to log into the server:
