Dear <?= Html::encode($user->username)?>,
  
Unfortunatly, we cannot accept your registration. 
This might have several causes. For example, we only accept the use of a professional email adress.
If you signed up with you private email, retry using your professional one.

The administator left the following comment: <?= Html::encode($user->comment)?>,

If you were rejected, but consider your request justified, please contact the user support:
<?php \Yii::$app->params ['feedbackMail']?>. 
  
Thank you!
