You can include the SPF/DKIM parameters in your DNS settings. SPF (Sender Policy Framework) is a DNS text entry which provides a list of servers that should be considered allowed to send emails for a specific domain.
How does SPF work?
Sender Policy Framework or SPF follows below steps to ensure security of your email sending domains.
- Your DNS has SPF records that list all of your domain’s authorized IP addresses or servers.
- Whenever an email is sent from your domain, the receiving email server checks these records.
- If the sender’s IP address (or server) matches one on the list, the email is authenticated. Emails that pass SPF authentication can reach their destination inboxes, while those that fail might not.
How does DKIM work?
- An email sent from your domain is signed with your private key.
- To verify the signature, the receiving email server retrieves the public encryption key found in the DKIM records on your DNS. Authentication occurs if the signature and key pairs match.
- If an attacker tried to modify the email during transit, this signature would fail to verify.
- The receiving server would see this as evidence of tampering and mark the email, protecting the end receiver from a potentially malicious email.
You can see both SPF and DKIM values in the “Domains” branch of the “Settings” section.
Include these records into your provider’s DNS settings – when you’re done with the implementation, come back to the domains section and click “Verify SPF and DKIM records” and “Check records“. If records were embedded correctly, you will see green checkmarks.
Here’s a video tutorial on how to find these records:
Each hosting solution has a different interface and various methods of how SPF and DKIM are configured. Therefore, we have collected some links of the most popular hosting solution supporting articles on how it’s done. Hope it’ll come in handy.
