/**
 * Logger is a SwiftMailer plugin, which allows passing of the SwiftMailer internal logs to the
 * Yii logging mechanism. Each native SwiftMailer log message will be converted into Yii 'info' log entry.
 *
 * In order to catch logs written by this class, you need to setup a log route for 'yii\swiftmailer\Logger::add' category.
 * For example:
 *
 * ~~~
 * 'log' => [
 *     'targets' => [
 *         [
 *             'class' => 'yii\log\FileTarget',
 *             'categories' => ['yii\swiftmailer\Logger::add'],
 *         ],
 *     ],
 * ],
 * ~~~
