Linux認(rèn)證系統(tǒng)管理：linuxmail命令發(fā)送郵件失敗

　　使用linux自帶的郵件功能測試郵件發(fā)送功能如下：

　　$ mail -s test xxx@163.com

　　sldkfjlskdjf[CTRL+D]

　　cc:

　　有時會出再提示:

　　You have a new mail in /var/spool/mail/root

　　并且在郵箱中看不到郵件;

　　解決辦法:

　　1.查看出錯的日志

　　$ tail -n 50 /var/spool/mail/root

　　2.修改DNS

　　$ vim /etc/resolv.conf

　　3.修改主機(jī)名【也可不做這一步】

　　$ sysctl kernel.hostname=newhostname

　　4.重啟郵件服務(wù)

　　$ service sendmail restart
