Email Authentication Tutorial

This tutorial covers the following topics:

Email authentication helps to prevent spam. The options are available in Site Tools > Email > Authentication attempt to equip email messages with verifiable information so that the email server can automatically detect the nature of incoming and outgoing messages. Enable these features to reduce the number of failed delivery notifications you receive when spammers forge messages from your domains. These features also stop spammers who forge messages that claim to be from your domains.

DKIM

DKIM allows your server to verify incoming email and prevent incoming spam messages. This feature ensures that incoming messages are unmodified and are genuinely from the indicated sender. To enable the use of DKIM for your domain names, go to the DKIM tab and click on Activate.

SPF

The SPF system allows you to authorize servers and IP addresses to send mail from your domains. This feature prevents outgoing spam messages and it is enabled by default for your domain name. Bear in mind that it will take effect only if your domain name is pointing to your SiteGround account:

You can also modify the default SPF record via the tool. You can add additional A records and MX servers to be allowed, block specific IPs, manage the include SPF list and the “all” parameter of the record. You can find out more about the SPF record syntax in the official documentation.
