cPanel script to enable SPF and DKIM via the command line

SPF and DKIM are two popular email authentication mechanisms. They prevent email spoofing as well as phishing attacks. SPF, short for Sender Policy Framework allows email servers to verify that incoming mail from a domain is sent from a legitimate source. On the other hand, DKIM short for DomainKeys Identified Mail relies on cryptographic signatures to verify the authenticity of the email message.

When we enable SPF and DKIM for a domain in cPanel, we can ensure that emails sent from that domain are authenticated and trusted by email servers. In other words, it prevents our emails from being marked as spam or rejected by recipient email servers.

Furthermore, enabling SPF and DKIM via the command line in cPanel allows for automation and scripting. This goes a long way in saving time and effort in managing multiple domains or accounts.

Additionally, it also offers a way to easily enable these authentication mechanisms when adding new domains to an account or during the domain setup process.

How to enable SPF and DKIM via the command line in cPanel

We can easily enable SPF and DKIM for a domain in cPanel via the command line, you can use the following script:

#!/bin/bash
# Define domain name and cPanel username
domain="example.com"
cpanel_user="cpanel_username"Copy Code

# Enable SPF for the domain
/usr/local/cpanel/bin/spf_installer $domain $cpanel_userCopy Code

# Enable DKIM for the domain
/usr/local/cpanel/bin/dkim_keys_install $domain $cpanel_userCopy Code

Here, we have to replace example.com with the domain name we want to enable SPF and DKIM for and cpanel_username with our actual cPanel username.

Then, we have to save the above script as enable_spf_dkim.sh. After that, we must make it executable by running the following command:

 chmod +x enable_spf_dkim.shCopy Code

Finally, run the scrips as seen here:

./enable_spf_dkim.shCopy Code

Now, SPF and DKIM will be enabled for the domain we specified in cPanel.
