1.安裝mailx

安裝mailx:

yum install mailx

 

vi /etc/mail.rc

set [email protected]
set smtp="smtps://smtp.qq.com:465"
set smtp-auth-user=12345678
set smtp-auth-password=xxxxxxx (郵箱賬號的客戶端授權碼，需要登陸自己的郵箱進行設定，不是郵箱密碼)
set smtp-auth=login
set ssl-verify=ignore
set nss-config-dir=/etc/pki/nssdb

 

測試：

echo test | mailx -v -s "test"  
 
[email protected]

2.生成certificate

解決報錯：

使用上面的配置，郵件是完全能夠發出去的，但是傳送郵件的時候會提示 “Error in certificate: Peer’s certificate issuer is not recognized.”提示，執行以下命令生成一個證書即可。

mkdir -p /root/.certs/
echo -n | openssl s_client -connect smtp.qq.com:465 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/.certs/qq.crt
certutil -A -n "GeoTrust SSL CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -A -n "GeoTrust Global CA" -t "C,," -d ~/.certs -i ~/.certs/qq.crt
certutil -L -d /root/.certs
 

生成完成之後，修改 mail.rc 郵件配置，修改 nss-config-dir 為上面命令生成的 /root/.certs，儲存即可

3.shell指令碼

建立一個shell指令碼如下：

#/bin/bash
#author:findyou
help(){
   echo "eg: $0 [Subject] [address] [content_file] [file]"
   echo ""
   exit 1
}

sub="the mail"

cDate=`date +%Y%m%d`

if [ ! -n "$1" ] ; then
    help
else
    mail_to=$1
    echo "      Send Mail to ${mail_to}"
fi

if [ ! -n "$3" ] ; then
    mail -s 'the mail' ${mail_to}<$2
else
    mail -s 'the mail' -a $3 ${mail_to}<$2
fi
