[Dovecot] Ownership and permissions for the index directory/filesystem

I recently upgraded from DC 1.1.15 to 1.2.6. The /var/dcindx index root
directory is:
drwxrwsrwt 3962 root sys 192512 Nov 13 11:56 ./
thus 3777.
It appears that the user index directories created under DC1.1 look like
this (here for /var/dcindx/cep):
drwx--S--- 5 cep sys 256 Nov 13 14:26 cep/
while those created under V1.2 look like:
drwx------ 3 lrenart sys 256 Nov 12 14:59 lrenart/
It seems that the first time that DC goes to do indexing, I now see this
error msg:
Nov 12 11:45:15 mercury mail:err|error dovecot: IMAP(bpyi): open(/var/spool/mail/bpyi) failed: Permission denied (euid=2586(bpyi) egid=2000(bard2) missing +w perm: /var/spool/mail)
...but never again...
Questions:
1) Are the ownership and permissions on the /var/dcindx index root
directory ideal or should they be something else?
2) Ideally what should the ownership and permissions be for individual
user subdirs? I create the user mail directories when creating a new
account, so it would be little extra trouble to create and set the
ownership and permissions.
I am currently using mbox mailbox format but will be migrating to
maildir over the next some months.

Now it's like an apartment in Bed-Stuy: you need three heavy duty
pick-proof locks, one of those braces that goes from the lock to the
floor, and bars on the windows.... ==== Stewart Dean, Unix System Admin,
