Question

我尝试用JavaMail发送电子邮件，但我收到了一个例外，我不知道发生了什么！

public class Mail 
{
private int port = 587;
private String host = "smtp.live.com";
private String from = "myusername@live.com";
private boolean auth = true;
private String username = "myusername@live.com";
private String password = "mypassword";
private Protocol protocol = Protocol.SMTPS;
private boolean debug = true;


@SuppressWarnings("incomplete-switch")
public void sendMail(String to, String subject, String body)
{
    Properties outlookProps = new Properties();
    outlookProps.put("mail.smtp.host", host);
    outlookProps.put("mail.smtp.port", port);

    switch (protocol) {
    case SMTPS:
        outlookProps.put("mail.smtp.ssl.enable", true);
        break;
    case TLS:
        outlookProps.put("mail.smtp.starttls.enable", true);
        break;
    }

    Authenticator authenticator = null;
    if (auth) {
        outlookProps.put("mail.smtp.auth", true);
        authenticator = new outlookAuthenticator();
    }

    Session session = Session.getInstance(outlookProps, authenticator);
    session.setDebug(debug);

    MimeMessage message = new MimeMessage(session);
    try {
        message.setFrom(new InternetAddress(from));
        InternetAddress[] toAddresses = {new InternetAddress(to)};
        message.setRecipients(Message.RecipientType.TO, toAddresses);
        message.setSubject(subject);
        message.setSentDate(new Date());
        message.setText(body);
        Transport.send(message);
    } catch (MessagingException ex) {
        ex.printStackTrace();
    }

}

class outlookAuthenticator extends Authenticator
{
        private PasswordAuthentication pa = new PasswordAuthentication(username, password);
        @Override
        public PasswordAuthentication getPasswordAuthentication() {
            return pa;
        }
}

我收到了这个例外：

我不知道被拒绝的权限是什么意思，是否可能是因为我的防病毒程序阻止它或类似的东西？请帮助！
