Openwrt使用mutt和msmtp实现发送邮件功能

环境

OpenWrt R22.6.16 / LuCI Master (git-22.180.58246-fb20b65)
使用lean源码编译

功能实现

1.安装软件包mutt和msmtp

如果在编译时没有选择mutt和msmtp，需要使用opkg安装

3
opkg update
opkg install msmtp
opkg install mutt

2.编辑/etc/msmtprc

# Example for a system wide configuration file                                  
                                                                                
# A system wide configuration file is optional.                                 
# If it exists, it usually defines a default account.                           
# This allows msmtp to be used like /usr/sbin/sendmail.                         
account default                                                                 
                                                                                
# The SMTP smarthost                                                            
host smtp.163.com           #smtp服务器的地址                                                    
                                                                                
# Use TLS on port 465         #是否加密传输                                                  
port 465                                                                        
tls on                                                                          
tls_starttls off                                                                
                                                                                
# Construct envelope-from addresses of the form "user@oursite.example"          
from xxxxxx@163.com               #发送放邮件地址                                          
auth login                                                                      
user xxxxxx@163.com               #发送放邮件地址                                         
password *********                   #邮件账号开启smtp时显示的令牌                                    
                                                                                
# Syslog logging with facility LOG_MAIL instead of the default LOG_USER         
syslog LOG_MAIL                                                                 
logfile /var/log/msmtp.log          #错误日志

3.编辑/etc/Muttrc (需要新建,注意大小写)

1

5
set from="xxxxxxxx@163.com"    #发送来源，如果不填163可能会拦截554 DT:SPM
set sendmail="/usr/bin/msmtp"
set use_from=yes
set realname="xxxxxxx"          #真实名称(收件人看到的发件人名称)
set editor="vim"

4.测试

1
echo "内容" | mutt -s "标题" xxxx@163.com  #收件人邮箱地址

5.shell脚本及定时发送(/bin/163mail位置无所谓)

#!/bin/sh
{

echo "To:<xxxxxxx@163.com>";       #收件人邮箱地址
 
echo "Date: `date '+%a, %d %b %Y %H:%M:%S %z'`";
echo "Subject: Current IP-Sat,`date '+%a, %d %b %Y %H:%M:%S '`";
echo ""
echo "The vwan1 IP is $(ip -4 addr show dev pppoe-vwan1 | awk '/inet / {print $2}')"；
echo "The vwan2 IP is $(ip -4 addr show dev pppoe-vwan2 | awk '/inet / {print $2}')"；
echo "The br-lan IPv6:";
echo "$(ip -6 addr show dev br-lan | awk '/dynamic / {print $2}' | cut -d/ -f1)"；
echo ""
echo "CPU temperature is:";
echo "$(sensors | grep Core)";
echo ""
echo "System process:";
echo "$(ps)";
} |mutt xxxxxxx@163.com -s "主题"    #收件人地址,shell脚本结束

通过crontab -e定时发送邮件
