dovecot - Mar 2010 - fchown error upgrading from 0.99 to 1.2

Hi there,
after upgrading from 0.99 to 1.2, the following errors appear in the error
log:
Mar 09 15:50:23 POP3(cwchbodega): Error:
fchown(/home/cwchbodega/mail/.imap/INBOX/dovecot.index.log.newlock, -1,
12(mail)) failed: Operation not permitted (egid=653(cwchbodega), group based

12(mail)) failed: Operation not permitted (egid=653(cwchbodega), group based

As I check the perms on the files, i see that:
/var/mail/cwchbodega
-rw-rw----  1 cwchbodega mail

and
/home/cwchbodega/mail/.imap/INBOX/
[root at mail INBOX]# ls -la /home/cwchbodega/mail/.imap/INBOX/

-rw-------  1 cwchbodega cwchbodega  13028 Mar  6 08:54 .imap.index.tree
[root at mail INBOX]#

Should I chown user:mail the contents of the INBOX folder?
and use perms of 0600 ?

thanks,

Most likely you don't really need this file to be group-rw by mail. It's
most likely just a potential security hole. The error goes away with:

chmod 0600 /var/mail/*

Maybe I just start bugging again those shadow-utils people to make 0600 the
default instead of 0660.
