На этом же сервере лежит веб приложение. Которое может отправлять письма на fgfdsfhjjhkj@yandex.com (этот имейл фигурирует в логах). Единственное место где может быть отправлено множество писем на мой взгляд - это страница восстановления пароля, но я эту функцию отключил. Может ли быть проблема с postfix-ом?
Может нужен конфиг postfix-а (main.cf)? Вот он:
