Is there anyone knows what the problem is ?

Check your SMTP configuration settings against below

<smtp deliveryMethod="Network" from="youraddress@example.com">
                         <network
                              host="smtp.example.com"
                              userName="username"
                              password="password"
                              port="25" />
                    </smtp>
               </mailSettings>
