shell 发邮件命令之 mail

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">目前最常用的就是mail命令了。 </span>

(sudo apt-get install mailutils)
也可手动下载安装： http://mailutils.org/download.html
简单一行命令实现发送邮件

echo 'content test' | mail -s "title test" -t abc@hello.com,efg@hello.com,123@world.com -a From:aaa@qq.com

内容由文件导入

mail -s "sh mail test" < file1.txt

带上附件

(uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t hello@aaa.com

内容 + 附件

(echo '1111111'; uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t hello@aaa.com

多个内容 +多个 附件

(echo '1111111'; echo '22222222'; uuencode file1.txt file1.txt; uuencode file2.txt file2.txt) | mail -s "title test" -t hello@aaa.com

Cent OS 系统上：

下载安装mailutils

wget ftp://ftp.gnu.org/gnu/mailutils/mailutils-2.2.tar.gz
解压进入

./configure

make && make install
yum install -y sendmail
yum install sharutils # 使用带附件功能

service sendmail start
查看sendmail启动没： ps aux |grep sendmail
测试： echo 'content test' | mail -s "title test" -t aaa@b.com
此时发觉只能给公司内部发邮件， 如果需要还能给外面的邮箱（比如我的qq邮箱）发邮件则还需要

vi /etc/mail/sendmail.mc

找到包含Addr的这一行：

DAEMON_OPTIONS(`Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl

修改Addr=0.0.0.0 ，表明可以连接到任何服务器

End

(data00和data03上已安装上)
