Here are some examples of how to set mail.smtp.port to 587 in different programming languages and email clients:

Java

Properties props = new Properties();
props.put("mail.smtp.host", "your-smtp-host");
props.put("mail.smtp.port", 587);
props.put("mail.smtp.auth", "true");
Session session = Session.getInstance(props, new javax.mail.Authenticator() {
    protected PasswordAuthentication getPasswordAuthentication() {
        return new PasswordAuthentication("your-email-username", "your-email-password");
    }
});

Python
