DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

How to Create a DKIM Certificate in Mail Assure – Solarwinds

• Open your Solarwinds control panel and log in.
• When using the Domain Level Control Panel, choose Outgoing > DKIM.
• Determine the DKIM key length
• Enter a DKIM selector.
• Click “Generate” a new private/public pair and save it.
