+    ## Description
+
+    An insecure SMTP connection can expose transmitted data to unauthorized access. This rule identifies if SMTP settings are configured to enforce secure connections.
+
+    ## Remediations
+
+    - **Do** enable SSL encryption in your SMTP configuration to secure the connection. This prevents unauthorized access to the data being transmitted.
+      ```python
+      EMAIL_USE_TLS = True
+      ```
