Dart 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.

Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // 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.
  final imap = CkImap();

  // Connect to an IMAP server.
  imap.ssl = true;
  imap.port = 993;
  try {
    imap.connect('imap.example.com');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Login
  try {
    imap.login('myLogin', 'myPassword');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Select an IMAP mailbox
  try {
    imap.selectMailbox('Inbox');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;

  // Fetch the email at the last sequence number.
  // (We are assuming the Inbox has at least 1 email)

    imap.fetchEmail(false, numEmails, false, email);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);

  // Disconnect from the IMAP server.
  imap.disconnect();

  // Create a new email.  The email we just read will be attached to this email.
