|
|
<p>Since iRedMail-0.9.1, it's able to restrict mail users to login from specified
|
|
IP addresses or networks.</p>
|
|
<p>Allowed IP/networks must be separated by comma. If the user tries to log in
|
|
elsewhere, the authentication will fail the same way as if a wrong password
|
|
was given.</p>
|
|
<p>Below sample usage shows how to restrict mail user <code>user@domaim.com</code> to login
|
|
from only IP address <code>172.16.244.1</code> or network <code>192.168.1.0/24</code>.</p>

|
|
sql> UPDATE mailbox SET allow_nets='172.16.244.1,192.168.1.0/24' WHERE username='user@domain.com';
|
|
</code></pre>
|
|
|
|
<p>To remove this restriction (allow to login from anywhere), just set
|
|
value of SQL column <code>mailbox.allow_nets</code> to NULL. WARNING: It must be NULL,
|
|
not empty string.</p>

<p>To allow user <code>user@domain.com</code> to login from IP <code>172.16.244.1</code> and network
|
|
<code>192.168.1.0/24</code>, please add new attribute <code>allowNets</code> to this user:</p>
|
|
<pre><code>allowNets: 192.168.1.10,192.168.1.0/24
|
|
</code></pre>
|
|
|
|
<p>To remove this restriction, just remove attribute <code>allowNets</code> for this user.</p>
