[Dovecot] Dovecot Newbie v1.1.10 + and shared folders.

[Harry Lachanas]

Hi all,

I finally manged to create somehow shared folders in dovecot imap ...

After a number trials I came up with this conf from my test server
#----------------------------------------------------------------------------------------------------------

#dovecot --build-options
SQL drivers: mysql
Passdb: checkpassword pam passwd passwd-file shadow sql
Userdb: nss passwd passwd-file prefetch sql static
#-----------------------------------------------------------------------------------------------------------
protocols = imap imaps
log_timestamp = "%Y-%m-%d %H:%M:%S "
ssl_cert_file = /etc/postfix/sasl/mycert.pem
ssl_key_file = /etc/postfix/sasl/mycert.pem
mail_location = maildir:~/Maildir

namespace private {
separator = /
prefix =

location = maildir:~/Maildir
inbox = yes
}
namespace public {
prefix = Public/
separator = /
location = 
maildir:/var/Public:INBOX=~/Maildir:INDEX=~/Maildir/p-index:CONTROL=~/Maildir/p-ctrl
hidden=no
subscriptions=no
inbox = no
}
namespace public {
prefix = Public2/
separator = /
location = 
mbox:/var/Public2/mboxes:INBOX=~/Maildir:INDEX=~/Maildir/p2-index:CONTROL=~/Maildir/p2-ctrl
hidden=no
subscriptions=no
inbox = no
}
mail_privileged_group = mail
mail_debug = yes
valid_chroot_dirs = /var/mail
protocol imap {
mail_plugins = convert
imap_client_workarounds = outlook-idle
}

protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}
auth default {
mechanisms = plain login
passdb pam {
}
userdb passwd {
}
user = root
socket listen {
client {
path = /var/spool/postfix/private/auth
mode = 0660
user = postfix
group = postfix
}
}
}
dict {
}
plugin {
}
#--------------------------------------------------------------------
However I observed that
a) dovecot-shared file is not honored unless located in inside the 
maildir stucture .... ( just above cur,tmp,new )
b) when mbox format is used dovecot-shared file does not get honored at 
all ... ( ie a user creates another mailbox in the directory ).
c) Is there a way to reject mbox or maildir file/dir creations by the 
users in a shared folder ??

I've used a mailbox format public namespace in order to be simple and 
have users dump undetected spam there for latter use in sa-learn --spam .

Please understand that I am quite new to this ( confused as well ), thus 
some of my questions might seem naive ( at least ) ..

Cheers
Harry.
