如何在java中发送ZOHO SMTP服务器邮件？

Question

I have been using ZOHO SMTP server for sending out email. but it was working in localhost server ,when deploying my code into AWS server it not going to be working,it is giving Exception like below..

javax.mail.MessagingException: Could not connect to SMTP host: smtp.zoho.com, port: 465; nested exception is: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)

My java code is :-

Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.zoho.com");
        prop.put("mail.smtp.port", 465);

        prop.setProperty("mail.smtp.user", username);
        prop.setProperty("mail.smtp.password", password);
        prop.setProperty("mail.smtp.auth", "true");
        // prop.setProperty("mail.pop3.socketFactory.class", SSL_FACTORY);
        prop.setProperty("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        prop.setProperty("mail.smtp.socketFactory.fallback", "false");
        prop.setProperty("mail.smtp.socketFactory.port", "465");
        // prop.put("mail.smtp.starttls.enable", "true");
        // prop.setProperty("mail.smtps.tls.enable", "true");

The above code is working in my localhost server (Tomcat). can any one please help to solve out this.

465 is SSL port. It looks like SSL certificate from ZOHO is missing in AWS. Download/obtain certificate from Zoho and import it on AWS's Keystore. It should solve the problem.
