Unfortunately, even if the website owner takes all available measures and makes the website as safe as possible for users, this will not protect him 100% from being blacklisted. Indeed, sometimes it is enough just to be on the same hosting or server with spammers or intruders. Your website can even get blocked if a website is adjacent to attackers in the pool of IP addresses. Therefore, it is important to know why websites end up in the DNSBL and how to avoid it.
DNS blacklists and how websites get into them
The most common reason a website gets listed in the DNSBL, oddly enough, is “bad neighbors”. An example of such blocking was given earlier, and therefore you need to always be prepared for the fact that your website is blocked for no apparent reason. Moreover, in this case, it is unlikely that it will be possible to immediately find out the reason for the blacklisting of the website. It will not be easy as well to prove that your website is definitely not the cause of IP blocking problems.
Another common reason for a website to be listed in the DNSBL is suspicious activity of the website’s mail server. As a rule, this reason stems from another, no less common – incorrect configuration of the website mail server. In both cases, the sources of problems can be completely different. For example, frequent mailings may be to blame for a website hitting the DNSBL. Or open ports. And so on and so forth.
Also, banal complaints from visitors are often the reason for blocking a website. It is enough for disgruntled users to send a few angry messages to the hosting owner. And after that, the hosting owners send the website to the DNSBL without any checks.
Ways to monitor and prevent website blacklisting
Even considering all of the above situations, your website may still be listed in the DNSBL. And it is especially critical if a website is blacklisted with a serious reputation and authority. Typically, local DNSBLs, as well as many ISP-related blacklists, sync with them. And then the website will definitely be blocked, and you will have to spend a lot of time communicating with support and providing proof of the website’s safety. Therefore, it is important to monitor the status of the website and prevent similar problems. Or at least be fully armed in case of problems.
The best way to do this is to use automated website monitoring systems such as HostTracker. At least because it is simply impossible to manually check each blacklist. In addition, this platform provides a wide range of different services for the full monitoring of websites for all indicators. Thanks to this approach, the webmaster can not only prevent the site from getting into the DNSBL. Also, the webmaster will be able to easily respond to any threats to the stability and functionality of the website. This will save time and money for the website owner. And it will also save the nerves of users, as well as the audience of the website in general.
