Implement a DKIM signature specific to our organization's sender domain (DMARC)

We would like to change our DMARC policy to reject any messages that are not using our DKIM signature to prevent others from using our domain in phishing schemes. Since Luminate Online generates their own DKIM signature, this would cause our emails sent from Luminate to be rejected by Email Service Providers that pay special attention to DMARC authentication. Can we obtain a unique DKIM signature from Blackbaud so we can publish that in our DNS server?
For the latest and most accurate information, please visit our email resource center .

After you publish it, it can take up to 48 hours for DNS changes to propagate through the entire internet.

Note: Blackbaud doesn’t provide support for publishing the file. If you need assistance, please work directly with your provider.
