dovecot - Jan 2007 - some Maildir files not honoring dovecot-shared

I'm using RC15 on Solaris 9.  The wiki indicates that when a dovecot-shared
file exists, "Dovecot uses the same permissions and GID when it creates
index files, dovecot-uidlist file, new mail files, etc."   In my case,
Dovecot *is* creating new index files based on dovecot-shared, but
dovecot-uidlist and individual message files don't completely match the
permissions/group template.  Specifically, dovecot-uidlist isn't
taking the group from dovecot-uidlist, and individual messages files
don't seem to be honoring dovecot-shared at all (group or permissions).

Here's an example; every file and directory below in .abusetest-in was
created by Dovecot *except* for dovecot-shared (I let Dovecot create cur,
new, tmp just to see what it would do, but I know that I can create and fix
the group and permissions on these directories myself in a sharing
situation):

glenn at tony:~/Maildir/.abusetest-in$ ls -lR
.:
total 34
drwx------   2 glenn    adm          512 Jan  9 09:58 cur/
-rwxrwx---   1 glenn    abuse          0 Jan  9 09:57 dovecot-shared*
-rw-rw----   1 glenn    adm           44 Jan  9 09:58 dovecot-uidlist
-rw-rw----   1 glenn    abuse        156 Jan  9 09:58 dovecot.index
-rw-rw----   1 glenn    abuse      10272 Jan  9 09:58 dovecot.index.cache
-rw-rw----   1 glenn    abuse        156 Jan  9 09:58 dovecot.index.log
drwx------   2 glenn    adm          512 Jan  9 09:58 new/
drwx------   2 glenn    adm          512 Jan  9 09:58 tmp/

./cur:
total 4
-rw-------   2 glenn    adm         1438 Jan  5 09:59
1168354728.P15661Q0M891161.tony:2,S

./new:
total 0

./tmp:
total 0
glenn at tony:~/Maildir/.abusetest-in$

I see in the RC16 release notes that there was a fix for the
dovecot-keywords file, but it doesn't mention these other files.  Is this a
bug, or am I misunderstanding how the dovecot-shared file should work?

Thanks very much,
Glenn

I don't know if the following is related to the above, but I thought I'd
include it here just in case.  After setting umask = 0007 in dovecot.conf,
dovecot-uidlist, dovecot.index, and dovecot.index.log are not created with
the new mask; however, the maildir parent directory, cur, new, tmp, and the
maildirfolder file *are* created with the new mask:

$ ls -l
total 12
drwxrwx---   2 glenn    adm          512 Jan 10 01:37 cur/
-rw-------   1 glenn    adm           44 Jan 10 01:37 dovecot-uidlist
-rw-------   1 glenn    adm          120 Jan 10 01:37 dovecot.index
-rw-------   1 glenn    adm           24 Jan 10 01:37 dovecot.index.log
-rw-rw----   1 glenn    adm            0 Jan 10 01:37 maildirfolder
drwxrwx---   2 glenn    adm          512 Jan 10 01:37 new/
drwxrwx---   2 glenn    adm          512 Jan 10 01:37 tmp/

I'm experimenting with using the umask setting for shared folders.  In the
case of sharing, won't the index files, etc. need to be readable by the
sharing group as well?

Thanks,
Glenn
