<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>

<p>If webmail is running on same server, and you want to allow user to login

from webmail, please allow IP <code>127.0.0.1</code> too.</p>

|

<p>To remove this restriction (allow to login from anywhere), just set
