How to set up DMARC for Hornetsecurity in Valimail

Updated over a week ago

This article covers the SPF and DKIM authentication processes for Hornetsecurity and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

Configuring DKIM authentication for your Hornetsecurity emails

In order to enable our DKIM validation for incoming emails or the DKIM signature for outgoing emails, it is first necessary that you set our CNAME record in the DNS zone of your domain.

Set the following two CNAME records in the DNS zone of your domain:

hse1._domainkey.DOMAIN.TLD CNAME hse1._domainkey.hornetsecurity.com

hse2._domainkey.DOMAIN.TLD CNAME hse2._domainkey.hornetsecurity.com

For DOMAIN.TLD, enter your domain.

You can enable validation as well as signing only if your domains have valid DKIM records.

You can then activate the desired functions in the Control Panel under Security Settings -> Email Authentication.

NOTE: If you manage you domain in Valimail, you will need to add the DKIM key/s on your domain's configuration page in the Valimail platform.
