Судя по всему, это попытка спама обратными письмами. То есть шлют письмо якобы с адреса (на который и нацелен спам), шлют на несуществующий ящик на сервере. При соответствующих настройках, сервер отвечает, уже на нацеленный адрес, что мол ваше письмо не доставлено, а в обратном письме присуствует спам. В общем всё нормально. Судя по логам.
