        prop.put("mail.smtp.auth", "true");

        prop.put("mail.smtp.starttls.enable", "true");

        prop.put("mail.smtp.port", port);



        Session session1 = Session.getDefaultInstance(prop, new Authenticator() {

            protected PasswordAuthentication getPasswordAuthentication() {

                return new PasswordAuthentication(from, password);

            }

        });



        Message mailmessage = new MimeMessage(session1);

        mailmessage.setFrom(new InternetAddress(from));

        mailmessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));

why don' you push your messages in activemq queue?if something happened activemq will take care.

@GauravRai1512 Because that doesn't give you anything a SMTP server wouldn't do anyway, but adds a lot of unneeded complexity?

Yeah, for that you also have to make connection of your queue with smtp server, flow would be from java code to activemq queue nd then smtp server.so instead of making direct connection with smtp you should use activemq as an interface. It will improve your performance.

Install SMTP service on computer, then set mail.smtp.host to localhost.

The SMTP service will attempt to resend email, until it gives up (configurable).

@EGary You'll just be using your machine as an SMTP relay server, only allowing relay from local apps, i.e. it won't be open to spam hackers.
