Answer 1

This JavaMail FAQ entry should help.

Try using MailSSLSocketFactory like this:

  MailSSLSocketFactory sf = new MailSSLSocketFactory();
  sf.setTrustAllHosts(true);
  props.put("mail.smtp.ssl.socketFactory", sf);

Answer 2

I had this problem with java 8. After updating this property problem solved

props.put("mail.smtp.ssl.trust", "smtp.gmail.com")

if used spring boot in application.property

spring.mail.properties.mail.smtp.ssl.trust = smtp.gmail.com

I think this will help.

Worked for me :)

Properties props = new Properties();
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.host", "smtp.companydomain.biz"); // 
        props.put("mail.smtp.auth", "true");
        props.put("mail.debug", "true"); 
        props.put("mail.smtp.starttls.enable", "true");`enter code here`
        props.put("mail.smtp.port", "25");
        props.put("mail.smtp.socketFactory.port", "25");
        props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
        props.put("mail.smtp.socketFactory.fallback", "true");

        MailSSLSocketFactory sf = null;
        try {
            sf = new MailSSLSocketFactory();
        } catch (GeneralSecurityException e1) {
            // TODO Auto-generated catch block
            e1.printStackTrace();
        }
        sf.setTrustAllHosts(true);
        props.put("mail.smtp.ssl.socketFactory", sf);

        Session mailSession = Session.getInstance(props, new javax.mail.Authenticator() {

            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("mail@companydomain.biz", "password");
            }
        });

        mailSession.setDebug(true); // Enable the debug mode

        Message msg = new MimeMessage( mailSession );

        //--[ Set the FROM, TO, DATE and SUBJECT fields
        try {
            msg.setFrom( new InternetAddress( "mail@companydomain.biz" ) );
        } catch (AddressException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        try {
            msg.setRecipients( Message.RecipientType.TO,InternetAddress.parse("myemailid@companydomain.biz") );
        } catch (AddressException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        //msg.setSentDate(new Date());
        try {
            msg.setSubject( "Hello World!" );
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //--[ Create the body of the mail
        try {
            msg.setText( "Hello from my first e-mail sent with JavaMail" );
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        //--[ Ask the Transport class to send our mail message
        try {
            Transport.send( msg );
        } catch (MessagingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }   
    }
