使用下面的代码，我无法发送电子邮件。没有抛出异常，但没有发送电子邮件。该代码是从运行在 Apache Tomcat 中的 servlet 中调用的。

该代码主要来自http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/上的在线示例。调试输出位于代码下方。

  public static boolean sendEmail(String to, final String from, String subject, String emailMessage) {
    final String username = from;
    final String password = MyUtilities.getSystemPWD(from);
    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.host", MyConfiguration.smtpServer);
    props.put("mail.smtp.port", MyConfiguration.smtpPort);
    Session session = Session.getInstance(props,
            new javax.mail.Authenticator() {

                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(username, password);
                }
            });
    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to));
        message.setSubject(subject);
        message.setText(emailMessage);
        Transport.send(message);

        System.out.println("Done");
    } catch (MessagingException me) {
        MyLogger.log("MyUtilities.sendEmail: Messaging error", me);
        Logger.getLogger(MyUtilities.class.getName()).log(Level.SEVERE, "MyUtilities.sendEmail: Messaging error", me);
        System.out.println("MyUtilities.sendEmail: Messaging error");
        return false;
    } catch (Exception ex) {
        MyLogger.log("MyUtilities.sendEmail: Messaging error", ex);
        Logger.getLogger(MyUtilities.class.getName()).log(Level.SEVERE, "MyUtilities.sendEmail: Messaging error", ex);
        return false;
    }
    return true;
}

从调试输出中可以清楚地看出，您的邮件服务器正在接受来自您的应用程序的消息。因此，您的程序或配置没有问题。如果邮件服务器从不发送邮件，您需要查看邮件服务器日志文件。在此之前，请查看收件人的垃圾邮件文件夹。

我遇到了（几乎）同样的问题，这是由于一些额外/不需要的 jars，请参阅 Send mail not working in Spring/Maven/Java 6 environment
