Доброго дня.
Из под рута всё работает.
Из под юзера выводится сабж.
Запустил с strace:

Гугл вытаскивает ссылки на багрепорт, но у меня не тот случай.
Из под рута ведь работает.
Где и что ещё можно посмотреть ?
и да, если из под этого юзера запустить /usr/bin/mutt -s «TEST2» email@domain.com - всё ок.
