Overview

This document describes how to add an SPF record to specify the server for sending emails. This is an efficient anti-spam solution.

Prerequisites

You have created the corresponding private domain. For details, see Creating Private Domain.

Directions

1. Log in to the Private DNS console and click Private Domain List on the left sidebar to enter the private domain list.
2. In the Private Domain List, click the name of the private domain for which you need to create an SPF record or DNS as shown below:
   
3. On the DNS Records tab, click Add Record and enter the following record value information as shown below:
   
   • Host: enter a subdomain. For example, when adding an SPF record for www.123.com, you can simply select www in the Host field. If you want to add an SPF record for 123.com, select @ in the Host field.
   • Record Type: select SPF.
   • Record Value: for example, v=spf1 include:spf.mail.qq.com ~all indicates that only the IP addresses in the A record and MX record of this domain have permission to send emails using this domain.
   • Weight: leave it empty.
   • MX Priority: leave it empty.
   • TTL: it is the cache time and 300s by default. The smaller the value, the faster the change to the record will take effect. You can enter an integer between 1 and 86400.
4. Click Save.
