JavaMail!

JavaMail is a popular open-source library for sending and receiving email in Java applications. It provides a simple and flexible way to interact with email servers and protocols, allowing developers to send, receive, and manipulate email messages.

Here are some key features of JavaMail:

SMTP and POP3 support: JavaMail supports both SMTP (Simple Mail Transfer Protocol) and POP3 (Post Office Protocol version 3) protocols, allowing you to send and receive email messages.
Email message manipulation: JavaMail provides classes for creating, parsing, and manipulating email messages, including headers, bodies, and attachments.
Email server connection: JavaMail allows you to connect to email servers, including Gmail, Yahoo, and Outlook, using various authentication mechanisms, such as username/password, OAuth, and SSL/TLS.
Multi-part messages: JavaMail supports sending and receiving multi-part messages, which can contain multiple attachments and alternative text formats.
Internationalization: JavaMail supports internationalization, allowing you to send and receive email messages in different languages and character sets.

Some common use cases for JavaMail include:

Sending automated emails: JavaMail can be used to send automated emails, such as password reset emails, order confirmations, and newsletters.
Email notifications: JavaMail can be used to send email notifications, such as alerts, reminders, and updates, to users or administrators.
Email integration: JavaMail can be used to integrate email functionality into web applications, mobile apps, or desktop applications.

To use JavaMail in your Java project, you'll need to:

Add the JavaMail library: Add the JavaMail library to your project's classpath or Maven dependencies.
Create a Session object: Create a Session object, which represents the connection to the email server.
Create a Message object: Create a Message object, which represents the email message you want to send or receive.
Set message properties: Set properties such as sender, recipient, subject, and body on the Message object.
Send or receive the message: Use the Session object to send or receive the Message object.

Here's an example of sending an email using JavaMail:

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

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

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

        // Set message properties
        message.setFrom(new InternetAddress("[email protected]"));
        message.addRecipient(Message.RecipientType.TO, new InternetAddress("[email protected]"));
        message.setSubject("Hello, World!");
        message.setText("This is a test email.");

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