You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: notification.go
    path of file: ./repos/arozos/src
    
    the code of the file until where you have to start completion: package main

import (
	"strconv"
	"time"

	fs "imuslab.com/arozos/mod/filesystem"
	notification "imuslab.com/arozos/mod/notification"
	"imuslab.com/arozos/mod/notification/agents/smtpn"
)

var notificationQueue *notification.NotificationQueue

func notificationInit() {
	//Create a n
    
func notificationInit() {
	//Create a new notification agent
	notificationQueue = notification.NewNotificationQueue()

	//Register the notification agents

	/*
		SMTP Notification Agent
		For handling notification sending via Mail
	*/

	//Load username and their email from authAgent
	userEmailmap := map[string]string{}
	allRecords := registerHandler.ListAllUserEmails()
	for _, userRercord := range allRecords {
		if userRercord[2].(bool) {
			userEmailmap[userRercord[0].(string)] = userRercord[1].(string)
		}
	}

	smtpnConfigPath := "./system/smtp_conf.json"
	if !fs.FileExists(smtpnConfigPath) {
		//Create an empty one
		smtpn.GenerateEmptyConfigFile(smtpnConfigPath)
	}

	smtpAgent, err := smtpn.NewSMTPNotificationAgent(*host_name, smtpnConfigPath,
		func(username string) (string, error) {
			//Translate username to email
			return registerHandler.GetUserEmail(username)
		})

	if err != nil {
		systemWideLogger.PrintAndLog("Notification", "Unable to start smtpn agent: "+err.Error(), nil)
	} else {
		notificationQueue.RegisterNotificationAgent(smtpAgent)
	}

	//Create and register other notification agents

	go func() {
		time.Sleep(10 * time.Second)
		return
		notificationQueue.BroadcastNotification(&notification.NotificationPayload{
			ID:            strconv.Itoa(int(time.Now().Unix())),
			Title:         "Email Test",
			Message:       "This is a testing notification for showcasing a sample email when DISK SMART error was scanned and discovered.<br> Please visit <a href='https://blog.teacat.io'>here</a> for more information.",
