How to Manage E-mail Deliverability Settings in cPanel

June 27, 2023 / cPanel & WHM

In this article, we will describe how to manage e-mail deliverability settings in cPanel which will help you to reduce unwanted e-mails.

  1. DomainKeys Identified Mail (DKIM)

    Here you can use DKIM to verify the incoming e-mail message is actually from the stated sender, and that message has been altered or not during the transit. When you enable DKIM, the sender will digitally sign a message using a private key. Here, the recipient uses DNS to retrieve the sender’s public key and it verify the message’s signature. If the signature is not valid, then the message will be assumed to be forged and spam.
    Follow the steps to manage DKIM settings-

    1. Login to your “cPanel Account”.
    2. Click on “Email Deliverablity”, from the search tool.
      Email
    3. Select the domain and click on “Manage”.
      Domain
    4. Under DKIM, here you can view the name/value pair for the DKIM DNS entry.
  2. Sender Policy Framework (SPF).
    SPF will help you to prevent spammers from forging messages which will implicate your domain as the sender. As a result, SPF will reduce the amount of bounce messages that you will receive. SPF uses DNS records which specify the mail servers and the IP addresses that are authorized to send the e-mail messages from a domain.
    Follow the steps to manage SPF settings:

    1. Log into your “cPanel Account”.
    2. Click on “Email Deliverability”, from the email section.
    3. Select the domain and click on “Manage”.
    4. Under SPF, here you can view the name/value pair for the SPF DNS entry.
  3. Reverse DNS (PRT records)
    PRT record is a DNS entry which enables resolving IP addresses to domain names. It is also called “Reverse DNS” as it is a typical DNS lookup that involves going the other way. Another method used for reducing spam is to confirm the domain name associated with a specific IP address.
    Follow the steps to manage Reverse DNS (PRT records):

    1. Log into your “cPanel”.
    2. Click on “Email Deliverablity”, from the email section.
    3. Select the domain and click on “Manage”.
    4. Under REVERSE DNS (PTR), here you can view the name/value pair for the PTR record entry.
    5. Here, you need to ask your web hosting provider to “add” a PTR record.

In this way, you can manage e-mail deliverability settings in cPanel.
