Still no joy

My account on the imap server
$ id stephen
uid=501(stephen) gid=100(users) groups=10(wheel),100(users),1000(cs)

shared account user
$ id cs
uid=1000(cs) gid=1000(cs) groups=1000(cs)

as user=stephen (some hidden files removed from listing)

$ ls -lA /var/spool/mail/public
total 20
drwxrwx--- 4 cs   cs    4096 Mar 10 21:26 cs
drwx------ 2 root root 16384 Mar 10 12:08 lost+found

$ ls -lA /var/spool/mail/public/cs
total 40
drwxrwx--- 6 cs cs 4096 Mar 10 21:26 mail

$ ls -lA /var/spool/mail/public/cs/mail

$ ls -lA /var/spool/mail/public/cs/mail/.Incoming
total 12
drwxrwx--- 2 cs cs 4096 Mar 10 21:01 cur

drwxrwx--- 2 cs cs 4096 Mar 10 21:01 new
drwxrwx--- 2 cs cs 4096 Mar 10 21:01 tmp

Now when I try to subscribe

Mar 10 21:37:19 scacifs02-lnx dovecot: IMAP(stephen):
opendir(/var/spool/mail/public/cs/mail) failed: Permission denied
Mar 10 21:37:19 scacifs02-lnx dovecot: IMAP(stephen): Connection closed

This make no sense to me.  I am a member if the cs group which has rwx
perms for all the directories from cs on down.  How can I not have
permission to open the directory?

In fact:

$ perl -e 'opendir DIR,"/var/spool/mail/public/cs/mail" or die
$!;@aa=readdir(DIR);close DIR;foreach(@aa){print "$_\n";}'
.
cur
new
.Incoming
..
tmp

So I do have permission to open the directory but dovecot doesn't
agree  (Is this a sign I should just give up on 1.0.7? :-)

My config changed a bit:

# 1.0.7: /etc/dovecot.conf
protocols: imaps
listen: *
ssl_cert_file: /etc/pki/dovecot/certs/scacifs02-lnx.dovecot.crt
