Can't get shared public folders working

[Randall Gellens]

I'm trying to use a shared public namespace.  Clients say it exists, 
but sieve scripts can't write to it.

The configuration in /etc/dovecot/conf.d/10-mail.conf:
# Shared namespace for Foo stuff
     namespace {
       type = public
       separator = '/'
       prefix = "#Foo/"
       location = 
maildir:/local/mnt/mail/shared:INDEXPVT=/local/mnt/mail/%n/shared:LAYOUT=fs

       # Use the default namespace for saving subscriptions.
       #subscriptions = no

       # List the shared/ namespace only if there are visible shared mailboxes.
       #list = children
     }

I created the location, owned by the vmail user:
     $ ls -ld /local/mnt/mail/shared
     drwxr-xr-x 4 vmail vmail 4096 Dec 11 12:38 /local/mnt/mail/shared

I created the subfolders, verified that they are there.  Also, I see that
Dovecot created a dovecot.mailbox.log file:
     $ ls -l /local/mnt/mail/shared
     total 12
     -rw-r--r-- 1 vmail vmail   96 Dec 11 12:38 dovecot.mailbox.log
     drwxr-xr-x 3 vmail vmail 4096 Dec 11 12:37 Foo-Bugs
     drwxr-xr-x 3 vmail vmail 4096 Dec 11 12:38 Foo-Patches

The dovecot.mailbox.log file is empty:
     $ more /local/mnt/mail/shared/dovecot.mailbox.log

The intermediate folder is empty:
     $ ls -l /local/mnt/mail/shared/Foo-Bugs/
     total 4
     drwxr-xr-x 5 vmail vmail 4096 Dec 11 12:36 Foo-Bugs-New

The mailbox has some folders in it:
     $ ls -l /local/mnt/mail/shared/Foo-Bugs/Foo-Bugs-New/
     total 12
     drwxr-xr-x 2 vmail vmail 4096 Dec 11 12:36 cur
     drwxr-xr-x 2 vmail vmail 4096 Dec 11 12:36 new
     drwxr-xr-x 2 vmail vmail 4096 Dec 11 12:36 tmp

They seem to be empty:
     $ ls -l /local/mnt/mail/shared/Foo-Bugs/Foo-Bugs-New/*
     /local/mnt/mail/shared/Foo-Bugs/Foo-Bugs-New/cur:

The Sieve log insists the mailbox doesn't exist:
     $ more /local/mnt/home/Foo-bugs/.dovecot.sieve.log
     sieve: info: started log at Dec 11 15:35:20.
     error: msgid=<p06240614d0afdab4a086@[99.111.97.136]>: failed to 
store into mailbox '#Foo/Q
     popper-Bugs/Foo-Bugs-New': Mailbox doesn't exist: 
#Foo/Foo-Bugs/Foo-Bugs-New.
     info: msgid=<p06240614d0afdab4a086@[99.111.97.136]>: stored mail 
into mailbox 'INBOX'.

But if I telnet into the server, the mailbox shows up:
     a1 list "" *
     * LIST (\HasNoChildren \Junk) "/" Junk
     * LIST (\Noselect \HasChildren) "/" #Foo
     * LIST (\Noselect \HasChildren) "/" #Foo/Foo-Patches
     * LIST (\HasNoChildren) "/" #Foo/Foo-Patches/Foo-Patches-New
     * LIST (\Noselect \HasChildren) "/" #Foo/Foo-Bugs
     * LIST (\HasNoChildren) "/" #Foo/Foo-Bugs/Foo-Bugs-New
     * LIST (\HasNoChildren) "/" INBOX
     a1 OK List completed.

And I can SELECT it:
     a2 select "#Foo/Foo-Bugs/Foo-Bugs-New"
     * FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
     * OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft 
\*)] Flags permitted.
     * 0 EXISTS
     * 0 RECENT
     * OK [UIDVALIDITY 1418343553] UIDs valid
     * OK [UIDNEXT 1] Predicted next UID
     * OK [NOMODSEQ] No permanent modsequences
     a2 OK [READ-WRITE] Select completed (0.006 secs).

So why can't the Sieve script store into it?
