How to go send java mail from localhost

To send a Java mail from localhost, you'll need to follow these steps:

Step 1: Set up your Java project

Create a new Java project in your preferred IDE (e.g., Eclipse, IntelliJ IDEA, NetBeans).
Add the Java Mail API (javax.mail) to your project. You can do this by adding the following dependency to your pom.xml file (if you're using Maven):
```
<dependency>
  <groupId>javax.mail</groupId>
  <artifactId>mail</artifactId>
  <version>1.6.2</version>
</dependency>
```
Step 2: Configure your mail server
Since you're sending mail from localhost, you'll need to configure a mail server to send the mail. You can use a local mail server like smtp4dev or mailhog.
For smtp4dev, download the executable from here and run it. This will start a local SMTP server on port 2525.
For mailhog, download the executable from here and run it. This will start a local SMTP server on port 1025.

Step 3: Write your Java code

Create a new Java class that will send the mail. For example, let's call it SendMail.java.

Import the necessary classes:

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

Create a Properties object to configure your mail server:

Properties props = new Properties();
props.put("mail.smtp.host", "localhost"); // or "smtp4dev" or "mailhog"
props.put("mail.smtp.port", "2525"); // or "1025"
props.put("mail.smtp.auth", "true");

Create a Session object using the Properties object:

Session session = Session.getInstance(props, new Authenticator() {
  @Override
  protected PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication("your-email-address", "your-password");
  }
});

Create a MimeMessage object to send the mail:

MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress("your-email-address"));
message.setRecipient(Message.RecipientType.TO, new InternetAddress("recipient-email-address"));
message.setSubject("Test Mail");
message.setText("This is a test mail sent from localhost");

Send the mail using the Transport object:
```
Transport.send(message);
```
Step 4: Run your Java code
Compile and run your SendMail.java class.
The mail should be sent to the recipient's email address.

Here's the complete code:

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class SendMail {
    public static void main(String[] args) {
        Properties props = new Properties();
        props.put("mail.smtp.host", "localhost");
        props.put("mail.smtp.port", "2525");
        props.put("mail.smtp.auth", "true");

        Session session = Session.getInstance(props, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("your-email-address", "your-password");
            }
        });

        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("your-email-address"));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress("recipient-email-address"));
        message.setSubject("Test Mail");
        message.setText("This is a test mail sent from localhost");

        Transport.send(message);
    }
}

Remember to replace your-email-address, your-password, and recipient-email-address with your actual email credentials and the recipient's email address.
