dovecot - Oct 2012 - index files created improperly in dovecot 1.2.16

Greetings,
It seems to be a problem that ive seen occasionally on the web with few 
results as to a solution, but im experiencing it as well.  Namely, dovecot 
creates index logs for users with a 600 permission, when it should create 
with a 700 permission.  

My indexes are stored in /var/indexes with the 
directory at 777 permission, the users are identified in MySQL.  The error 
is as follows:

Oct 23 09:03:13 mailer01 dovecot: POP3 (johnr at testing.com): 
stat(/var/indexes/j/johnr at testing.com/.INBOX) failed: Permission 
denied (euid=10509305(x10509305) egid=81607(pg199275) missing +x perm: 
/var/indexes/j)

the permissions of /var/indexes/j are 700, owned by the euid and egid 
effectively.  the only file that does not have this permission is in 
/var/indexes/j/johnr at testing.com/.INBOX/dovecot.index.log, at 600.
