### messages
| Method | Path | Description |
|--------|------|-------------|
| GET | /messages/{messageId} | Retrieves the raw content of an in-transit email message, in MIME format. |
| POST | /messages/{messageId} | Updates the raw content of an in-transit email message, in MIME format. This example describes how to update in-transit email message. For more information and examples for using this API, see Updating message content with AWS Lambda. Updates to an in-transit message only appear when you call PutRawMessageContent from an AWS Lambda function configured with a synchronous Run Lambda rule. If you call PutRawMessageContent on a delivered or sent message, the message remains unchanged, even though GetRawMessageContent returns an updated message. |
