 * MessageInterface is the interface that should be implemented by mail message classes.
 *
 * A message represents the settings and content of an email, such as the sender, recipient,
 * subject, body, etc.
 *
 * Messages are sent by a [[MailerInterface||mailer]], like the following,
 *
 * ~~~
 * Yii::$app->mail->compose()
 *     ->setFrom('from@domain.com')
 *     ->setTo($form->email)
 *     ->setSubject($form->subject)
 *     ->setTextBody('Plain text content')
 *     ->setHtmlBody('<b>HTML content</b>')
 *     ->send();
 * ~~~
