/**
* 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.
*
* This logger will be automatically created and applied to underlying [[\Swift_Mailer]] instance, if [[Mailer::$enableSwiftMailerLogging]]
* is enabled. For example:
*
* ```php
* [
* 'components' => [
* 'mailer' => [
* 'class' => 'yii\swiftmailer\Mailer',
* 'enableSwiftMailerLogging' => true,
* ],
* ],
* // ...
* ],
* ```
*
*
* In order to catch logs written by this class, you need to setup a log route for 'yii\swiftmailer\Logger::add' category.
* For example:
*
* ```php
* [
* 'components' => [
* 'log' => [
* 'targets' => [
* [
* 'class' => 'yii\log\FileTarget',
* 'categories' => ['yii\swiftmailer\Logger::add'],
* ],
* ],
* ],
* // ...
* ],
* // ...
* ],
* ```
