package main

import (
	"fmt"
	"log"

	"github.com/badoux/checkmail"
)

func main() {
	err := checkmail.ValidateHost("abc@163.com")
	if err != nil {
		log.Fatalf("邮箱验证失败: %v", err)
	}
	fmt.Println("邮箱域名验证通过")
}

2024/11/15 22:39:51 邮箱验证失败: dial tcp 103.129.252.43:25: i/o timeout

Non-authoritative answer:
163.com	mail exchanger = 50 163mx00.mxmail.netease.com.
163.com	mail exchanger = 10 163mx01.mxmail.netease.com.
163.com	mail exchanger = 10 163mx02.mxmail.netease.com.
163.com	mail exchanger = 10 163mx03.mxmail.netease.com.

the most reason is you should use the 465 port not use the 25 port when in combodia. but I don't know how to fix your code. thank you.

func TestValidHost(t *testing.T) {
err := ValidateHost("abc@163.com")
if err != nil {
t.Fatalf("邮箱验证失败: %v", err)
}
t.Log("邮箱域名验证通过")
}
兄弟，你是不是引错版本了，现在master最新分支clone下来测试是可以的
