How to send a mail from java with out sender

In Java, you can send an email without a sender (also known as "anonymous" or "no-reply" email) using the JavaMail API. Here's an example:

Step 1: Add the JavaMail API to your project

You'll need to add the JavaMail API to your project. You can do this by adding the following dependency to your pom.xml file (if you're using Maven) or by downloading the JAR file and adding it to your project's classpath:

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.2</version>
</dependency>

Step 2: Create a JavaMail session

Create a JavaMail session using the following code:

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

// Create a JavaMail session
Session session = Session.getDefaultInstance(new Properties(), null);

Step 3: Create a MimeMessage

Create a MimeMessage object to represent the email:

// Create a MimeMessage
MimeMessage message = new MimeMessage(session);

Step 4: Set the recipient and subject

Set the recipient and subject of the email:

// Set the recipient
message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress("[email protected]"));

// Set the subject
message.setSubject("No-reply email");

Step 5: Set the message body

Set the message body:

// Set the message body
message.setText("This is a no-reply email.");

Step 6: Send the email

Send the email using the Transport class:

// Send the email
Transport.send(message);

Here's the complete code:

import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;

public class NoReplyEmail {
    public static void main(String[] args) {
        // Create a JavaMail session
        Session session = Session.getDefaultInstance(new Properties(), null);

        // Create a MimeMessage
        MimeMessage message = new MimeMessage(session);

        // Set the recipient
        message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress("[email protected]"));

        // Set the subject
        message.setSubject("No-reply email");

        // Set the message body
        message.setText("This is a no-reply email.");

        // Send the email
        Transport.send(message);
    }
}

Note that this code sends an email without a sender (i.e., the From field is empty). This is not recommended in most cases, as it can lead to deliverability issues and make it difficult for recipients to respond to the email. If you need to send no-reply emails, it's recommended to use a valid sender email address and include a clear disclaimer indicating that the email is automated and cannot be replied to.
