How Do I Adjust DKIM Settings?
Overview
DomainKeys Identified Mail (DKIM) is an email authentication technique that adds a digital signature to the email header. It verifies that the email was sent from an authorized sender and has not been tampered with during transit. DKIM uses public-key cryptography to create a signature that can be verified by the recipient's email server.
DKIM plays a crucial role in email security. It provides three key benefits:
-
Prevents email spoofing – DKIM prevents email spoofing by verifying the authenticity of the sender's email address.
-
Protects email integrity – DKIM protects email integrity by making sure that the email has not been tampered with during transit.
-
Improves email deliverability – Emails that fail DKIM verification are more likely to be marked as spam or rejected by the recipient's email server, thereby improving the deliverability of your emails and reducing the chance of them being marked as spam.
Adjusting DKIM Settings
Follow the steps below to enable and adjust the DKIM Settings.
- Log in to your Account Manager.
- Click Email on the left navigation menu.
- Select the mailbox on the Email page where you wish to adjust the DKIM settings, then click Manage.
- Click DKIM Manager to launch the DKIM Control Panel.
- Select Configure with auto-generated keys to enable DKIM.
- Select the DMARC policy:
- The DMARC policy indicates to your receivers that your messages are DKIM-protected. It also tells them what to do if messages do not pass, are flagged as junk, or are rejected.
- It is recommended that DMARC policies be introduced gradually. Begin with a setting of None, move to Quarantine, and finally to Reject. Monitor your DMARC reports at each stage to ensure messages are signed and not spoofed.
Please take note of the following DMARC options:
- None – No action needed, useful for monitoring
- Quarantine – Message should be set aside
- Reject – Message should be rejected
- Type in the email address you would like to receive the DMARC reports at in the Send Reports to field. The email address must be under the domain that you are managing.
You have enabled DKIM, and your DNS settings will be automatically updated as long as your domain name is on our nameservers.
If your domain is not on our nameservers, click the link that says View DNS TXT Record Information after you have enabled DKIM and provide these records to your nameserver host.
