#### Email
The Orange box has port 25 closed so as to limit the amount of spam that could be sent from a compromised home connection.
The remaining solution to host one own's email at home is to route it through the Orange SMTP servers.
To that end, one has to edit the postfix configuration file with the following command:
```bash
sudo nano /etc/postfix/main.cf
```
then, add the SMTP Orange server as a relay on the associated line:
```bash
relayhost = smtp.orange.fr
```
restart Postfix :
```bash
sudo service postfix restart
```
