 MIP SDK supports decryption and encryption for email messages. Both .msg files, generated by Outlook or Exchange, and .rpmsg files are supported by the SDK although via slightly different methods.

-> As of MIP SDK 1.17, .eml files are supported. Handling is similar to .msg for labeling/protection scenarios and to .rpmsg for inspection scenarios, depending on the container format.

 Common use cases for this scenario are:
 
 - Decrypt mail and attachments for data loss prevention (DLP) inspection.

 - Construct `mip::FileHandler` that points to the file to be labeled.

+## Labeling of EML Files
+
+As of MIP SDK 1.17, .eml files are supported. Handling is similar to .msg for labeling/protection scenarios and to .rpmsg for inspection scenarios, depending on the container format. When working with .eml files, you must set the *enable_eml_file_type* flag instead of *enable_msg_file_type*. If you've created a `FileEngineSettings` object called *engineSettings*, you'd set this property in .NET as follows:
+
+```csharp
+engineSettings.CustomSettings = new List<KeyValuePair<string, string>>();
+engineSettings.CustomSettings.Add(new KeyValuePair<string, string>("enable_eml_file_type", "true"));
+```
+
 Refer to [Quickstart: List labels](quick-file-list-labels-cpp.md) for information on how to list labels.
