To use the GreenMail Maven plugin, you'll need to add the following dependencies to your pom.xml file:

<dependencies>
    <dependency>
        <groupId>com.icegreen</groupId>
        <artifactId>greenmail</artifactId>
        <version>1.6.6</version>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>com.icegreen</groupId>
        <artifactId>greenmail-maven-plugin</artifactId>
        <version>1.6.6</version>
        <scope>test</scope>
    </dependency>
</dependencies>

You'll also need to configure the plugin in your pom.xml file:

<build>
    <plugins>
        <plugin>
            <groupId>com.icegreen</groupId>
            <artifactId>greenmail-maven-plugin</artifactId>
            <version>1.6.6</version>
            <executions>
                <execution>
                    <goals>
                        <goal>start</goal>
                        <goal>stop</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <server>smtp.gmail.com</server>
                <port>587</port>
                <username>your-email-username</username>
                <password>your-email-password</password>
            </configuration>
        </plugin>
    </plugins>
</build>

In this example, we're configuring the plugin to use an SMTP server, port 587, and specifying the email username and password.

Once you've configured the plugin, you can run your GreenMail tests as part of your Maven build process by executing the mvn test command. The plugin will start the GreenMail server, run your tests, and then stop the server.
