This article covers the SPF and DKIM authentication processes for Bullhorn and how they are managed in Valimail Enforce. 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 Bullhorn emails

Create a CNAME record

1. To create a CNAME record, log in to your DNS Hosting Provider and locate the CNAME section in the admin tool.

Each hosting provider has a different interface, but this is typically found under DNS. Example: Click Manage > Click DNS > Add CNAME record.

2. Format the CNAME record as follows, replacing mydomainname with your domain name:

Host: bh._domainkey.mydomainname.com

Points to: bh._domainkey.bullhornmail.com

Important: If you manage DKIM in Valimail, you will need to add the above CNAME DKIM key ion your domain's configuration page in Valimail Enforce.
