This article describes how to manage e-mail deliverability settings in cPanel to help reduce unwanted e-mail (spam). These settings include:
You can use DKIM to verify that an incoming e-mail message is actually from the stated sender, and that the message has not been altered during transit. When DKIM is enabled, the sender digitally signs a message using a private key. The recipient uses DNS to retrieve the sender's public key and verify the message's signature. If the signature is invalid, then the message is assumed to be forged and therefore spam.
To manage DKIM settings, follow these steps:
SPF helps prevent spammers from forging messages that implicate your domain as the sender. As a result, SPF can also reduce the amount of bounce messages that you receive (also known as backscatter spam). SPF uses DNS records that specify the mail servers and IP addresses that are authorized to send e-mail messages from a domain.
To manage SPF settings, follow these steps:
Under SPF, you can view and modify the name/value pair for the SPF DNS entry.
If you have a shared hosting or reseller hosting account, confirm that the raw SPF record includes one of the following configuration lines:
If one of these configuration lines is not in the raw SPF record, follow these steps:
A PTR record is a DNS entry that enables resolving IP addresses to domain names. This is called “reverse DNS” because a typical DNS lookup involves going the other way—returning the associated IP address for a given hostname. Verifying the domain name for a given IP address is another technique that is used to help reduce spam.
To manage reverse DNS settings, follow these steps:
