Почему maldet не отправляет отчет по почте?

В некоторых установках может возникнуть указанная ниже ошибка из-за отсутствия команды mail: /usr/local/maldetect/internals/functions: строка 647: -s: команда не найдена

Если у вас установлен sendmail, вы можете использовать diff ниже, чтобы добавить sendmail поддержка отправки по электронной почте:
