Mail Delivery System

Здраствуйте, ко мне на почту, на которой зарегестрирован сайт, стали приходить странные письма. Отписался на хостинг они сказали что возможно кто-то пытается спамить от моего имени. сегодня пришло порядком 500 писем. Вот их примерное содержание:

Письмо 1:

 be delivered to one or more recipients. It's attached below.

 If you do so, please include this problem report. You can

 delete your own text from the attached returned message.
