 ## Using a Microsoft Entra application with access to the Azure Communication Services Resource for SMTP
 
-Application developers who build apps that send email using the SMTP protocol need to implement secure, modern authentication. Azure Communication Services does this by leveraging Entra application service principals. Combining the Azure Communication Services Resource and the Entra application service principal's information, the SMTP services undertakes authentication with Entra on the user's behalf to ensure a secure and seamless email transmission.

 ### Requirements for SMTP AUTH client submission
 
-- **Authentication**: Username and password authentication is supported using Entra application details as the credentials. The Azure Communication Services SMTP service will use the Entra application details to get an access token on behalf of the user and use that to submit the email. Because the Entra token isn't cached, access can be revoked immediately by either changing the Entra application client secret or by changing the access controls for the Azure Communication Services Resource.

 - **Azure Communication Service**: An Azure Communication Services Resource with a connected Azure Communication Email Resource and domain is required.
 - **Transport Layer Security (TLS)**: Your device must be able to use TLS version 1.2 and above.
 - **Port**: Port 587 is required and must be unblocked on your network. Some network firewalls or ISPs block ports because that's the port that email servers use to send mail.
