Thanks Steffen. I went the quick'n'dirty way described at :
http://wiki2.dovecot.org/SharedMailboxes/Symlinks and I must say it works fine
as far as I have tested.
Here's what I did :
$ cd /var/vmail/algerian-radio.dz/a.chaouche/
$ ln -s /var/vmail/backup.algerian-radio.dz/a.chaouche/
.shared.a_chaouche@backup_algerian-radio_dz <---- change "." to "_"
If I didn't change the dots they would appear as subfolder separators to
dovecot (Maildir++ specs ? )
If you do this then a.chaou...@algerian-radio.dz can do whatever he wants with
a.chaou...@backup.algerian-radio.dz mailbox. We don't want this. We want him to
only read the mail, not delete it. For this, he needs two permissions : reading
of course and listing, because he needs to list the emails in order to choose
which one he wants to read. If he doesn't have the listing permission then the
MUA would get an error when it tries to list all the messages in the inbox.
We do this by adding a dovecot-acl file in the mailbox we want to share :
root@messagerie[10.10.10.20] /var/vmail/backup.algerian-radio.dz/a.chaouche #
cat dovecot-acl
user=a.chaou...@algerian-radio.dz lr
root@messagerie[10.10.10.20] /var/vmail/backup.algerian-radio.dz/a.chaouche #
This says that user a.chaou...@algerian-radio.dz has the "l" right (listing)
and the "r" right (reading).
You can make sure that it's setup as expected with the acl tool :
root@messagerie[10.10.10.20] ~ # doveadm acl get -u
a.chaou...@algerian-radio.dz INBOX.shared.a_chaouche@backup_algerian-radio_dz
ID Global Rights
user=a.chaou...@algerian-radio.dz lookup read
root@messagerie[10.10.10.20] ~ #
1. No need for SQL tables
2. No need for dictionary mappings
3. No need for doveadm acl commands
Yassine.

looks fine for me,

you are using the dot as separator, that is:
shared/a.chaouche@backup. should spell
shared.a.chaouche@backup.
However, because there are dots in the username, too, this probably won't
work, because Dovecot probably picks up "a" as username.
