How to Handle Email Deliverability Settings using cPanel August 28, 2024

In this article, we will explain how to handle email deliverability settings using cPanel.

Managing email deliverability settings in cPanel helps ensure your genuine emails reach recipients’ inboxes while reducing spam and bounce rates.

DomainKeys Identified Mail (DKIM)

DKIM allows you to verify that an incoming email is truly from the claimed sender and check if the message has been altered during transit. When DKIM is enabled, the sender digitally signs the message using a private key. The recipient then retrieves the sender’s public key through DNS to verify the message’s signature. If the signature is invalid, the message is flagged as potentially forged or spam.”

Follow these steps to manage DKIM settings:

1. Log in to your cPanel account.
2. Use the search tool to find and click on Email Deliverability.
   
3. Select the domain you want to manage, then click Manage.
   
4. Under the DKIM section, you can view the name/value pair for the DKIM DNS entry.
   

Sender Policy Framework (SPF)

SPF helps prevent spammers from forging emails that appear to come from your domain, reducing the number of bounce messages you receive. SPF works by using DNS records to specify the mail servers and IP addresses authorised to send emails on behalf of your domain.

Follow these steps to manage SPF settings:

1. Log in to your cPanel account.
2. In the Email section, click on Email Deliverability.
3. Select the domain you want to manage and click Manage.
4. Under the SPF section, you can view the name/value pair for the SPF DNS entry.
   

Reverse DNS (PTR Records)

A PTR record is a DNS entry that allows IP addresses to be resolved into domain names, which is why it’s often referred to as “Reverse DNS.” Unlike typical DNS lookups, Reverse DNS works in the opposite direction. This method can also help reduce spam by verifying the domain name associated with a specific IP address.

Follow these steps to manage Reverse DNS (PTR) records:

1. Log in to your cPanel account.
2. In the Email section, click on Email Deliverability.
3. Select the domain you want to manage and click Manage.
4. Under the Reverse DNS (PTR) section, you can view the name/value pair for the PTR record entry.
5. To add a PTR record, contact your web hosting provider for assistance.
   

This way, you may manage email deliverability settings in cPanel to help reduce unwanted emails.
