CentOS 6.5 經過命令行安裝發送郵件

1.安裝sendmail：

yum install sendmail

2.安裝mailx：

yum install mailx -y

 

3.編輯發送的配置文件：

vi /etc/mail.rc
#在最後添加如下配置：
set from="991769422@qq.com" smtp="smtp.qq.com"
set smtp-auth-user="991769422@qq.com" smtp-auth-password="******"
set smtp-auth=login

4.測試郵件發送：

#1)  無郵件正文
  mail -s "主題"  收件地址
  mail -s "測試"  991769422@qq.com
 

#2) 有郵件正文

 mail -s "主題"  收件地址< 文件(郵件正文.txt)
 mail -s "郵件主題"  991769422@qq.com < /data/test.txt
 echo "郵件正文" | mail -s 郵件主題  收件地址
 echo "郵件正文內容" | mail -s "郵件主題"  991769422@qq.com
 cat test.txt | mail -s 郵件主題  收件地址 
 cat  /data/test.txt | mail -s "郵件主題"  991769422@qq.com
 

#3)  帶附件
 mail -s "主題"  收件地址  -a 附件 < 文件(郵件正文.txt) 
 mail -s "郵件主題"  991769422@qq.comm -a /data/test.tar.gz < /data/test.txt
