Hello, i received a mail from the support about my problem but i can't reply to that.
The mail says :
[...]If my answer did not resolve your issue, or you would like further assistance on this issue, please reply to this email. By

But everytime when i try to answer i receive a Delivery Status Notification (Failure) and i don't know what to do!
