Send email using SMTP STARTTLS.

Send email using SMTP STARTTLS. With STARTTLS, the SMTP client connects to the SMTP server on port 25 (non-SSL) and then issues a STARTTLS command to convert the connection to a secure TLS channel. 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.

  // The mailman object is used for sending and receiving email.
  final mailman = CkMailMan();

  // Set the SMTP server.
  mailman.smtpHost = 'smtp.mymailserver.com';

  mailman.smtpUsername = 'myLogin';
  mailman.smtpPassword = 'myPassword';

  mailman.startTLS = true;

  // Create a new email object
  final email = CkEmail();

  email.subject = 'This is a test';
  email.body = 'This is a test';
  email.from = 'Chilkat Support <support@chilkatsoft.com>';
  email.addTo('Chilkat Admin', 'admin@chilkatsoft.com');

  try {
    mailman.sendEmail(email);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  try {
    mailman.closeSmtpConnection();
  } on ChilkatException {
    print('Connection to SMTP server not closed cleanly.');
  }

  print('Mail Sent!');
