(Node.js) Forward by Attaching the Existing Email to a New Email

Demonstrates how to forward an email by attaching the email to a new email.

This example reads an email from an IMAP server, attaches the email to a new email, and sends the new email.

Note: This example requires Chilkat v11.0.0 or greater.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS
