The DKIM standard is an email authentication method that is designed to detect email spoofing, primarily phishing attacks. The DKIM standard uses a public/private key system in which a message signature is attached to a message in the sending server in the form of a header field. This allows the receiver to cryptographically verify that the message has not been altered since it was sent from the sending server.
Creating a DKIM Record for Fusemail SecureSMART / VIPRE Security
To enable DKIM signing for your outbound emails using DKIM follow the steps below:
Login to your Fusemail account
In the portal navigate to Service Settings > Outbound Relay > Outbound DKIM Signing
Select if wish to use 1024 or 2048 bit key (*2048 is recommended)
Click on the Generate button
Fusemail will generate your DKIM public and private keys
Now you need to access your DNS to publish the DKIM record for the public key
Login to your DNS management console, navigate to the DNS Records section and create a new TXT record for your DKIM public key
Copy and paste the generated DKIM record into your domain’s DNS
In the Hostname box, enter the "Key Selector" text string from the VIPRE Email Security portal followed by the literal string ._domainkey.
In the value field, paste the "TXT value" shown in VIPRE
Once your DNS has processed the changes, click on the Validate button next to your domain names on your Fusemail or VIPRE account
If all domains pass validation you will be able to click on Enable DKIM to enable DKIM authentication for your domains
