我有一个注册脚本，用户可以在我的网站上创建。我真的很挣扎与电子邮件被发送一个巨大的延迟，这意味着注册链接已经过期之前，任何用户得到他们的电子邮件。

    if (isset($_POST['n_register']))
    {
        $mail = trim($db->EscapeString($_POST['reg_mail']));
        $mail_re = trim($db->EscapeString($_POST['reg_mail_re']));
        if (!preg_match("/^[a-zA-Z_\\-][\\w\\.\\-_]*[a-zA-Z0-9_\\-]@[a-zA-Z0-9][\\w\\.-]*[a-zA-Z0-9]\\.[a-zA-Z][a-zA-Z\\.]*[a-zA-Z]$/i", $mail))
        {
                    $errorMsg = $langBase->get('home-08');
                }
                elseif ($mail !== $mail_re)
                {
                    $errorMsg = $langBase->get('home-09');
                }
                elseif ($db->GetNumRows($db->Query("SELECT id FROM `[users]` WHERE `email`='".$mail."' LIMIT 1")) > 0)

                    $errorMsg = 'You should already have an activation email from us.  Check the spam box, if not, contact us.';
                }
                elseif (!isset($_POST['acc_tos']))
                {

                }
                else
                {
                    $extra = array(
                        'mail' => $mail,
                        'enlist' => isset($_GET['e']) ? $db->EscapeString($_GET['e']) : $ref_id,

                    $tempID = substr(sha1(uniqid(rand())), 0, 6);
                    $db->Query("INSERT INTO `temporary` (`id`, `playerid`, `area`, `expires`, `time_added`, `extra`)VALUES('".$tempID."', '".$mail."', 'register', '10000', '".time()."', '".serialize($extra)."')");

                    mail($mail, $admin_config['game_name']['value'].' » Game Regsitration', 'href="'.$config['base_url'].'?side=signup&amp;step=2&amp;v='.$tempID.'">'.$config['base_url'].'?side=signup&amp;step=2&amp;v='.$tempID.'</a>
                                            <br />
                                            This link will remain active until <b>'.View::Time(time()+10000, true).''.$admin_config['game_name']['value'].'

有人看到这里有什么问题吗？也许电子邮件文本需要更长一些？在这个脚本的中间显然有一些html。
谢谢！
