为了测试,我如何获得一个已知的坏IP,一个在DNSBL上的IP?我搜索过已公布的黑名单,但没有找到。我猜公布名单会对垃圾邮件发送者有帮助,或者有其他坏的副作用。8.8.8.8 not listed by bl.spamcop.net8.8.8.8 not listed by dul.dnsbl.sorbs.net
= gethostbyname($check)) error_log('PHP Security: [DNSBL] - ' .die('Put a detailed error here so the client knows why they have been blocked');}
似乎唯一的问题是DNSBL
