Как посылать ошибки крона на несколько email?
Очень просто, в самом верху crontab -e перечисляем через запятую адреса получателей:
Источник: man 5 crontab.
MAILTO=email1@domain.ru,email2@domain.ru
MAILTO may also be used to direct mail to multiple recipients by separating recipient users with a comma. If MAILTO is defined but empty (MAILTO=""), no mail will be sent. Otherwise mail is sent to the owner of the crontab.
Источник: man 5 crontab.
xset на CentOS
yum install -y xorg-x11-server-utils
Коля, спасибо! Я уж из сил выбился искать этот пакет.
Postfix: выборка всех получателей, кому письма не были доставлены
for i in `find /var/spool/postfix/defer/ -type f`; do cat $i | grep recipient | sed 's/=/ /' | awk '{print $2}'; done | sort | uniq
Такой командой очень удобно ловить юзеров, у кого указан кривой/не рабочий ящик.
