/languages/zh_tw/admin/shop_config.php

添加

$_LANG['cfg_desc']['service_email'] = '多個郵箱地址請用半形逗號分隔。';

/flow.php中以下發送新訂單提醒郵件代碼

send_mail($_CFG['shop_name'], $_CFG['service_email'], $tpl['template_subject'], $content, $tpl['is_html']);

改為

$arrEmail = explode("," ,$_CFG['service_email']);
foreach($arrEmail as $arrEmailValue)
{
    send_mail($_CFG['shop_name'], $arrEmailValue, $tpl['template_subject'], $content, $tpl['is_html']); //發給多個客服
}
