SPF, DKIM & DMARC parameters
You need to include Sender.net SPF, DKIM and DMARC parameters in your Domain DNS settings.
How does SPF work?
SPF (Sender Policy Framework) is a DNS text entry that provides a list of servers that should be considered allowed to send emails for a specific domain. SPF follows the below steps to ensure the 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 SPF, DKIM, DMARC 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 “Set up DNS records” and “Check SPF, DKIM and DMARC record“. If records were embedded correctly, you will see green checkmarks.
