Explanation

This script performs the following operations:

1. SOAP Parse: SOAP message coming from request body is parsed
2. Email Information Extraction: Recipient, sender, subject, and content information are extracted from SOAP message
3. Validation: Sender and recipient information is checked
4. Email Sending: Email is sent via SMTP
5. SOAP Response: Operation result is returned as response in SOAP format

This script should be run on the request line (Request Policy) because it uses the requestBodyTextFromClient and requestErrorMessageToTargetAPI variables.
