React Native Requires Chilkat v11.0.0+

Forward by Attaching the Existing Email to a New Email

See more Email Object Examples

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.

React Native

import { Email, Imap, MailMan } from '@chilkat/react-native'

async function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // Read the 1st (most recent) email in an Inbox.
  const imap = new Imap();

  // Connect to an IMAP server.
  imap.ssl = true;
