CentOS 7을 새로 설치했습니다(Howtoforge에 대한 이 가이드를 따랐습니다).https://www.howtoforge.com/perfect-server-centos-7-apache2-mysql-php-pureftpd-postfix-dovecot-and-ispconfig3) 그리고 sendmail이 있습니다. 문제는 sendmail이 이메일 전달을 중단한 이후입니다. 이렇게 하면 작동하고 대기열에 있는 모든 메일을 보냅니다. 그런데 어떤 이유로 이메일 전송이 다시 중단됩니다.
cd /etc/mail
make
make restart
이메일 전송에 실패했을 때 나오는 문구입니다
