阻止 Web 表单中对 AOL 电子邮件地址的自动回复

if (strpos($email,'@aol.com') == false) {
    //send auto response
}

澄清一下：

//send message 1 and save result in success var (either true for success,
// or false for fail
$success = mail($message1 <SNIP>...
//conditionaly send message2, no need to check success on this one
if (strpos($email,'@aol.com') == false) {
    mail($message2 <SNIP>...
}
if ($success){
//show success message
}else{
//fail message
}

编辑 2好的，所以我认为你需要读一本关于PHP的好书，WROX的书通常写得很好。还要使用一个半体面的IDE，它会为你突出显示更明显的错误。JetBrains php storm 很棒，或者如果你不想付钱，netbeans 相当不错。

也就是说，我已经在这里为您清理了代码：

    //Collect contact form data
    //Check Special Field
    //Email ASC & Webmaster
    //Email Sender
    //Redirect to thank you page
    require_once($_SERVER['DOCUMENT_ROOT'].'/includes/functions.php');
    /********  CONTACT DATA **********/
    $name = stripslashes($_POST['name']);

    $spamcheck = stripslashes($_POST['email']);
    //if spamcheck isnt blank exit page, no need for error message to user, as its a spam bot
    if ($spamcheck!=="") {
        exit;
    }

我还没有检查过这个，但应该没问题。

您需要更改发送邮件的脚本，如下所示：

$noResponceDomains = array("aol.com", "more.domain"); // recommended to make a separate config
$domain = end((explode("@", $email))); // $email - user's email
if(!in_array($domain, $noResponceDomains)){
    // send you mail
}
