Security features

NOTE

You can change the SMTP port number using Web Based Management. This is useful if your ISP (Internet Service Provider) implements the “Outbound Port 25 Blocking (OP25B)” service.

If you can use both POP before SMTP and SMTP-AUTH, we recommend choosing SMTP-AUTH.

If you choose POP before SMTP for the SMTP Server Authentication Method, you need to configure the POP3 settings. You can also use the APOP method if needed.
