[Courier-imap] Cannot show message on a shared directory

[De L. G. <G.D...@eu...>]

Hello all,

I create a shared directory under courier-imap : here the commands

cd /home/Groups/Mail
maildirmake -S Eurofer
maildirmake -s write,group -f Environment         Eurofer

On the config file maildirshared I add :
Eurofer /home/Groups/Mail/Eurofer

I restart the imad services

>From my linux box, I start kontact and firefox.
I see the shared/Eurofer folder, but grayed
The shared/Eurofer/Environment is in normal mode.

>From my Inbox, I copy a message to shared/Eurofer/Environment
On the server the message is on the right place.
Under : home/Groups/Mail/Eurofer/.Environment/cur/mesg

But I not see the message into Th or kontact :-(

What is missing ?

Thanks in advance
Guy
