因为自己在开发的时候遇到了，解决方式就是移动端不发送邮箱验证。

修改 class_member.php 文件：

// if ($sendurl) {// 原代码
if ($sendurl && !defined('IN_MOBILE')) {// 非移动端才发送邮件
    $hashstr = urlencode ( authcode ( "$_GET[email]\t$_G[timestamp]", 'ENCODE', $_G ['config'] ['security'] ['authkey'] ) );
    $registerurl = "{$_G[siteurl]}member.php?mod=" . $this->setting ['regname'] . "&hash={$hashstr}&email={$_GET[email]}";
    $email_register_message = lang ( 'email', 'email_register_message', array (
            'bbname' => $this->setting ['bbname'],
            'siteurl' => $_G ['siteurl'],
            'url' => $registerurl
    ) );
    if (! sendmail ( "$_GET[email] <$_GET[email]>", lang ( 'email', 'email_register_subject' ), $email_register_message )) {
        runlog ( 'sendmail', "$_GET[email] sendmail failed." );
    }
    showmessage ( 'register_email_send_succeed', dreferer (), array (
            'bbname' => $this->setting ['bbname']
    ), array (
            'showdialog' => false,
            'msgtype' => 3,
            'closetime' => 10
    ) );
}
$emailstatus = 0;
if ($this->setting ['sendregisterurl'] && ! $sendurl) {
    $_GET ['email'] = strtolower ( $hash [0] );
    $this->setting ['regverify'] = $this->setting ['regverify'] == 1 ? 0 : $this->setting ['regverify'];
    if (! $this->setting ['regverify']) {
        $groupinfo ['groupid'] = $this->setting ['newusergroupid'];
    }
    $emailstatus = 1;
}

// 移动端，由于不发送邮件进行邮箱验证，则邮件状态为未激活
if(defined('IN_MOBILE')) $emailstatus = 0;
