SPA (Secure Password Authentication) is a propriety Microsoft protocol used with the Outlook email client. As SPA is proprietary to Microsoft and is not widely adopted, Hawk Host does not offer SPA support on our shared, reseller, or semi-dedicated hosting services.
We recommend that clients use SSL/TLS authentication when configuring their email clients. For more details on configuring an email client, please refer to our KB article: How to create and configure email acounts
