在我们公司的一台服务器上，/usr/lib/sendmail 突然停止工作。
我们在几个脚本（由 oracle 用户拥有和运行）中调用它，但它们都无法发送电子邮件，即使手动也不起作用。
服务器是：SunOS 5.10 Generic_Virtual sun4v sparc sun4v
oracle:/home/oracle $ ls -ltr /usr/lib/sendmail
-r-xr-sr-x 1 root smmsp 1064920 Jan 16 2013 /usr/lib/sendmail
下面以暂定发送邮件为例：
cat /etc/hosts | /usr/lib/sendmail -f [email protected] -t [email protected]
这是详细模式下的输出：
oracle@myserver:/home/oracle $ cat /etc/hosts | /usr/lib/sendmail -v -f [email protected] -t [email protected]

另外，我查看了 /var/log/syslog，找不到任何错误/警告消息，只有 mail.info，这就是我在 /var/mail/oracle 中找到的内容
