	sendTo := strings.Split(email.to,";")
	done := make(chan error,1024)

	go func() {
		defer close(done)
		for _,v := range sendTo {

			str := strings.Replace("From: "+USER+"~To: "+v+"~Subject: "+email.subject+"~~","~","rn",-1) + email.msg

			err := smtp.SendMail(
				SERVER_ADDR,auth,[]string{v},[]byte(str),)
			done <- err
		}
