linux發送郵件態度好慢

Linux認證系統管理：linuxmail命令發送郵件失敗

使用linux自帶的郵件功能測試郵件發送功能如下：

$ mail -s test [email protected]

sldkfjlskdjf[CTRL+D]

cc:

有時會出再提示:

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

並且在郵箱中看不到郵件;

解決辦法:

1.查看出錯的日誌

$ tail -n 50 /var/spool/mail/root

2.修改DNS

$ vim /etc/resolv.conf

修改成可用的DNS，這個地方的修改保存後即生效;

3.修改主機名【也可不做這一步】

$ sysctl kernel.hostname=newhostname

4.重啟郵件服務

$ service sendmail restart
