After activating the DMARC Manager and storing the NS entries within your DNS records (described under DMARC Manager -> Domains -> DKIM -> ‘View setup instructions’), the DKIM settings page displays the available options for the DKIM configuration. It is possible to add a new public key there. If you do not yet have your own DKIM key and do not wish to purchase your own key, you can use our DKIM keys.

To set this up, simply use the ‘+ Add new public key’ option to create two new entries with the record type ‘CNAME’, which contain the following information:

• Selector: hse1
Record Type: CNAME 
Record Value: hse1._domainkey.hornetsecurity.com
• Selector: hse2
Record Type: CNAME 
Record Value: hse2._domainkey.hornetsecurity.com

When using the DMARC Manager, the CNAME entries do not have to be additionally stored in your DNS records due to the NS entry.

After successful verification, all emails receive a DKIM signature.
