Email Certificate Hosting

To send secure email using Direct Messaging, the public email certificate must be hosted in DNS. Open Dental offers public email certificate hosting or you can host the public certificate elsewhere. To obtain a certificate, see Email Certificate.

To host the certificate with Open Dental, you must register the certificate using the registration tool. One certificate can be registered for a particular email address at one time.

  1. Open the Edit Email Address window for the email address you want to register. In the Main Menu, click Setup, Manage, Email, then double click on the email address.
  2. Click Certificate.
  3. Click Send Code. You will see the following message once the code is successfully sent.
  4. The email may take a few minutes to show up in your Email Inbox. Open the email to see the verification code. It will look similar to the following:
