如何在php中实现垃圾邮件黑名单检查？

Question

有很多dns已经运行了垃圾邮件发送者的集中黑名单，我有他们的名单，但我如何连接到他们，并提供域名并检查我的ip是否在他们的黑名单中？谢谢。

有没有办法使用php连接到列表并检查我的ip？谢谢。

Answer 1

我只使用了sorbs，但我认为它们都使用相同的模式。

您必须执行包含反向IP (例如: 32.45.12.10.socks.dnsbl.sorbs.net)的DNS查询，然后读取IP。如果发现匹配，则Sorbs将返回127.0.0.X (X是找到它的列表)。

因此，对于假设的IP地址，如12.32.145.12：

$ip = '12.32.145.12';
$reversedIp = implode('.', array_reverse(explode ('.', $ip)));
$host = $reversedIp.'.socks.dnsbl.sorbs.net';
$response = gethostbyname($host);

如果您的$response以127.0.0.开头，那么它将被sorbs列入黑名单。

您可以遍历您的列表，并针对每个黑名单服务调整算法。
