+## Install a local MTA
+
+The easiest option would be to disable the listener on port 25/tcp.
+
+**Postfix** users disable the listener by commenting the following line (starting with `smtp` or `25`) in `/etc/postfix/master.cf`:
+```
+#smtp      inet  n       -       -       -       -       smtpd
+```
+Restart Postfix after applying your changes.

 ## Sender and receiver model

 When a mailbox is created, a user is allowed to send mail from and receive mail for his own mailbox address.
