二、邮件发送远程备份
首先安装上面下载的文件，然后做下面的配置
vi /etc/Muttrc
set sendmail=”/usr/bin/msmtp -a your_account”
set realname=”your_email”
set use_from=yes
set editor=”vim”
MSMTP
创建user_home/.msmtprc和 user_home/.msmtp.log,分别为配置和日志文件。
vi msmtprc
account default
host smtp.domain.com
from your_email_address
tls on
auth on
user user_name@domain.com
password your_password
account default : dominic
由于password是明码，所以我们需要修改此文件的权限。
chmod 600 .msmtprc
到这里，你可以使用mutt来发送邮件了，我们测试一下。
echo “test” |mutt -s “my_first_test” anyone@163.com -c anytwo@163.com
-s “subject”
-c “carbon-copy”
观察.msmtp.log文件，如果有错会在日志文件中被报告出来，当然，成功发送的日志也会出现在此日志文件内。
编写如下脚本

#!/bin/bash
