本文以Centos7主机为例

安装依赖包
yum install dos2unix

|---|----------------------| | 1 | yum install dos2unix |

将我原来mailx脚本内容（https://blog.whsir.com/post-4387.html）
vi /etc/zabbix/alertscripts/mailx.sh

|---|--------------------------------------| | 1 | vi /etc/zabbix/alertscripts/mailx.sh |

#!/bin/bash echo "$3" | mail -s "$2" "$1"

|-----|--------------------------------------------| | 1 2 | #!/bin/bash echo "$3" | mail -s "$2" "$1" |

改成
#!/bin/bash FILE=/tmp/mailxtmp.txt echo "$3" > $FILE dos2unix -k $FILE mail -s "$2" "$1" < $FILE

|-----------|----------------------------------------------------------------------------------------------------| | 1 2 3 4 5 | #!/bin/bash FILE=/tmp/mailxtmp.txt echo "$3" > $FILE dos2unix -k $FILE mail -s "$2" "$1" < $FILE |

即可
