To begin the DKIM authentication process for your sending domain(s), log into your Professional account and navigate to Admin > System Settings > Setup > Email Authentication.
Enter your sending domain into the text field and click Get Instructions for customized DNS instructions. These steps are typically completed by your DNS admin or IT professional, so it is recommend they have access to log in to Professional. Once the 2 CNAME records are added to your DNS, return back to the Email Authentication page to run a test .
NOTE: The configuration won't be completed until the authentication test passes in your account.
Click the TEST button to see if the domain has passed authentication. If so, you'll see a message indicating the domain has passed the authentication test. The domain will then be added to the list on that page which can be deleted or retested if any changes need to be made.
NOTE: If the authentication test indicates that the domain has failed, you can try the following troubleshooting steps: See CNAME Troubleshooting for DKIM.
You can follow the same steps above for any additional domains that will be used to send through Professional. You will see each of the active/authenticated domains listed in your authentication settings.
If there is more than one account (child accounts) being used to send mail, you have the option of either making the parent account the default manager for DKIM entries or allow each child account to add and make changes to domains sent through their account. If you check the box to make the parent account the default, then email authentication settings will be used across all child accounts and only the parent account will have the rights to make changes.
SPF is configured on the bounce address "informz.net", so no additional steps are needed. However, you could add "include:informz.net" to your existing SPF record for receivers still checking SPF on the "from" address (i.e., Sender-ID which is deprecated). See SPF and Sender ID to learn more.
