zabbix 基于sendmail发送邮件相关问题

先看一下脚本

#!/bin/bash
to=$1
subject=$2
body=$3
from=3011741665@qq.com
smtp=smtp.qq.com
passwd=xxxxxxxxx
echo `date "+%y-%m-%d %H:%M:%S"` 发送方:$from 接收方:$to 主题:$subject 邮件内容:$body  >>  /tmp/sendmail.log
/usr/local/bin/sendEmail -v  -f 3011741665@qq.com -t ${to} -s 14.17.57.241 -u ${subject} -o message-content-type=html -o message-charset=utf8 -xu ${from} -xp ${passwd} -m "${body}"   -o tls=auto >> /tmp/sendmail.log 2>&1

 直接通过sendmail命令和脚本执行是没有问题,通过zabbix web界面测试就不行

查看了sendmail的日志报错是这样的,

ERROR => Connection attempt to smtp.qq.com:25 failed: IO::Socket::INET: Bad hostname 'smtp.qq.com'

 这里google里好多, 修改了dns,改了hosts解析

 都不行, 最后我把脚本里的smtp.qq.com改为用dig解析的ip,在测试就没有问题了,记录一下;
