如果不指定-r(发邮件地址),且你的主机名不是xxx.com,可能会报如下错误:

错误是550 MI:IMF 发信人电子邮件地址不合规范
使用文件进行邮件发送:
date | mail -r flying@yflying.com -s ‘SN_IP info TEXT ‘ uttflying@163.com wanglei@flying.com < /root/cobbler/sn.log mail命令的语法如下: Usage: mail [-iInv] [-s subject] [-c cc-addr] [-b bcc-addr] to-addr ... [-- sendmail-options ...] mail [-iInNv] -f [name] mail [-iInNv] [-u user]
