## 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 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 `SETACL` command, 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`.
|
||
|
|
|
||
|
|
```
|
||
|
|
# mysql -uroot -p
|
||
|
|
mysql> USE vmail;
|
||
|
|
mysql> SELECT * FROM share_folder;
