# Quarantine clean emails sent from/to certain local user
|
||
|
|
|
||
|
|
Update [Amavisd config file](./file.locations.html#amavisd), ask it to listen on one additional network port
|
||
|
|
`10030` (you're free to use another port), and one additional `policy_bank`:
|
||
|
|
|
||
|
|
```
|
||
|
|
$inet_socket_port = [10024, 9998, 10030];
|
||
|
|
|
||
|
|
$interface_policy{'10030'} = 'QUARANTINE';
|
||
|
|
$policy_bank{'QUARANTINE'} = {
|
||
|
|
clean_quarantine_method => 'sql:',
|
||
|
|
final_destiny_maps_by_ccat => {CC_CLEAN, D_DISCARD},
|
||
|
|
};
|
||
|
|
|
||
|
|
$clean_quarantine_to = 'clean-quarantine';
|
||
|
|
```
|
||
|
|
|
||
|
|
Restart Amavisd service.
|
||
|
|
|
||
|
|
* Append below content to Postfix config file `/etc/postfix/master.cf`, ask
|
||
|
|
Postfix to listen on one additional network port `10026` (you're free to use
|
||
|
|
another port):
|
||
|
|
|
||
|
|
```
|
||
|
|
127.0.0.1:10026 inet n - - - - smtpd

|

```
|
||
|
|
|
||
|
|
* Restart Postfix service.
|
||
|
|
|
||
|
|
```
|
||
|
|
service postfix restart
|
||
|
|
```
|
||
|
|
|
||
|
|
* To quarantine all emails sent from/to `user@domain.com`, set its per-user
|
||
|
|
transport to `smtp:[127.0.0.1]:10026`.
|
||
|
|
|
||
|
|
Now all emails sent from/to `user@domain.com` will be quarantined into SQL
|
||
|
|
database (specified in Amavisd config file, parameter `@storage_sql_dsn`).
|
||
|
|
|
||
|
|
Send an email to `user@domain.com` for testing:
|
||
|
|
|
||
|
|
```
|
||
|
|
# echo "mail body" | mail -s "test subject" user@domain.com
|
||
|
|
```
