發送電子郵件時發生SSL異常

Question

我正在嘗試通過Java應用程序發送電子郵件。 我正在嘗試從托管服務提供商（cyberhost.in）提供的電子郵件帳戶發送電子郵件。 每當我運行應用程序時，都會收到ssl異常。

1）代碼

public class Email {
    public static void main(String[] args) throws UnsupportedEncodingException {
        Properties props = new Properties();
        props.put("mail.smtp.host", "v1.cyberns.net");
        props.put("mail.smtp.socketFactory.port", "465");
        props.put("mail.smtp.socketFactory.class",
                "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.auth", "true");
        props.put("mail.smtp.port", "465");

        Session session = Session.getDefaultInstance(props,
                new javax.mail.Authenticator() {
                    protected PasswordAuthentication getPasswordAuthentication() {
                        return new PasswordAuthentication("admin@heyywassup",
                                "********");
                    }
                });

        try {

            Message message = new MimeMessage(session);
            message.setFrom(new InternetAddress("admin@heyywassup.com",
                    "heyywassup"));
            message.setRecipients(Message.RecipientType.TO,
                    InternetAddress.parse("amlan@ymail.com"));
            message.setSubject("Testing Subject");
            message.setText("Dear Mail Crawler,"
                    + "\n\n No spam to my email, please!");

            Transport.send(message);

            System.out.println("Done");

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }
}

2）異常

Answer 1

也許是Java的答案：為什么SSL握手會產生“無法生成DH密鑰對”異常？ 幫助您。 使用Java 1.7.08或更高版本應該可以解決問題。
