Mailbox sharing (Sharing IMAP folder with other users)
!!! note
* Since iRedMail-`0.9.0`, mailbox sharing are enabled by default, you don't
need to modify any config file.
* Since iRedMail-`0.7.0`, mailbox sharing related settings are configured
in Dovecot but not enabled, what you need to do is enabling `acl` plugin
as mentioned below.
* Do not mistake "shared folders" for "public folders". For shared folders,
users must select which folder they want to share and with who, using an
interface, like IMAP command line or the ones available with Roundcube
webmail or SOGo and SOGo connectors.
Enable mailbox sharing
To enable mailbox sharing, please make sure you have plugin acl enabled
in Dovecot config file /etc/dovecot/dovecot.conf like below:
- For Dovecot-1.2:
# Part of file: /etc/dovecot/dovecot.conf
protocol lda {
mail_plugins = ... acl
}
protocol imap {
mail_plugins = ... acl imap_acl
}
- For Dovecot-2.x:
# Part of file: /etc/dovecot/dovecot.conf
mail_plugins = ... acl
protocol imap {
mail_plugins = ... imap_acl
}
Restarting Dovecot service is required.
Test shared folder
Example: share from@domain.ltd's Sent folder to user testing@domain.ltd.
!!! warning
Do not forget the dot before each IMAP command.
# telnet localhost 143 # <- Type this.
* OK [...] Dovecot ready.
. login from@domain.ltd passwd # <- Type this.
# Login with full email address and password
. OK [... ACL ..] Logged in
. SETACL Sent testing@domain.ltd rli # <- Type this.
# Share folder `Sent` with user testing@domain.ltd,
# with permissions: read (r), lookup (l) and insert (i).
. OK Setacl complete.
^] # <- Press `Ctrl + ]` to exit telnet.
telnet> quit
Log into Roundcube webmail or SOGo as user testing@domain.ltd, you should
see the shared folder.
Some more details:
-
After you shared folder with
SETACLcommand, dovecot will insert a record in MySQL database.- With OpenLDAP backend, it's stored in
iredadmin.share_folder. - With MySQL/MariaDB/PostgreSQL backends, it's stored in
vmail.share_folder.
- With OpenLDAP backend, it's stored in
# mysql -uroot -p
mysql> USE vmail;
mysql> SELECT * FROM share_folder;
