我成功完成了validation of mail address，但我想要一些关于验证电子邮件地址的建议。要点是当用户输入电子邮件 ID 时，应该检查它是真实的还是只是假的 ID。有什么建议吗？

You can only check whether entered E-mail id is validate or not using regular expression, its not possible to check whether id is exists or not? as per my knowledge.

不，此设施不可用。只有当您拥有自己的邮件服务器时，您才能验证您有权检查邮件 ID 是否有效。或者当您拥有其他服务器时，您才可以获取所有其他邮件服务器的镜像，然后您可以验证，因此，如果您只是邮件 ID 的用户，那么您可以验证邮件 ID 是否有效。

您只能通过模式检查来验证邮件 ID 的正确格式。

玩得开心

public static void main(String[] args) throws Exception {
 String email = null;
 String dns = null;

 BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter email address to validate: ");
email = reader.readLine();
System.out.print("Enter DNS hostname to perform domain validation (e.g. ns.myhost.com): ");
dns = reader.readLine();
// create EmailInspector instance
EmailInspector inspector = new EmailInspector();

// enable debugging
inspector.setDebug(true);

// set DNS server
inspector.setNameserver(dns);

// set validation level
inspector.setEmailInspectionLevel(inspector.DOMAIN_VALIDATION);

// validate email
inspector.validate(email);
}

}






 .  Create new EmailInspector instance.
    .  Enable debugging.
    .  Set DNS server to be used for looking up domains.
    .  Set validation level.
    .  Validate email address.

Properties props = System.getProperties();

    props.put("mail.smtp.user", senderEmail);
    props.put("mail.smtp.host", "smtp.gmail.com");
    props.put("mail.smtp.port", "465");
    props.put("mail.smtp.starttls.enable", "true");
    props.put("mail.smtp.debug", "true");
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.socketFactory.port", "465");
    props.put("mail.smtp.socketFactory.class", 
          "javax.net.ssl.SSLSocketFactory");
    props.put("mail.smtp.socketFactory.fallback", "false");

    // Required to avoid security exception.
    email.MyAuthenticator authentication = 
          new email.MyAuthenticator(senderEmail,senderMailPassword);
    Session session = 
          Session.getDefaultInstance(props,authentication);
    session.setDebug(true);
