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.
