Postfix在启动时给了我这个错误：

请帮助 – 这是紧急的
您需要返回并重新阅读您的错误消息。
Oct 8 17:00:57 cheese-ubuntu postfix/postqueue[24106]: warning: Mail system is down -- accessing queue directly Oct 8 17:00:59 cheese-ubuntu postfix/postqueue[24117]: warning: Mail system is down -- accessing queue directly Oct 8 17:01:00 cheese-ubuntu postfix/postqueue[24122]: fatal: Cannot flush mail queue - mail system is down
说这一切。 您的邮件服务没有正常运行。
请记住，SysV初始化脚本执行状态pipe理 ，而不是进程pipe理 。 国家pipe理处理系统的状态; 过程pipe理是国家pipe理的一个子集，只关注对长期运行过程的监督。
完全有可能“启动”服务，SysV将服务标记为正在运行，但服务将会崩溃。 所以现在你有服务“运行”，但实际上不是。 停止服务，然后启动它，然后观看日志：
/etc/init.d/postfix stop ; /etc/init.d/postfix start ; tail -f -n100 /var/log/messages
