Understanding the SORBS Spam Blacklist: A Comprehensive Guide on How to Remove Your IP Address from Their List


Many businesses rely on email as a critical part of their day-to-day operations. 


But, if your emails keep ending up in the spam folder or being blocked altogether, you may have found out that one or more of your IP addresses are listed on SORBS Spam blacklist. 


If you’re trying to figure out why this happened and how to get off the list then you’ve come to the right place! 


In this blog post, we will give an overview of what the SORBS blacklist is, explain why your IP gets blacklisted by SORBS, explore how it can affect deliverability rates, and ultimately look at steps you can take to delist yourself from said list.



What is SORBS Spam Blacklist?


SORBS (Spam and Open Relay Blocking System) is a DNS-based blacklist (DNSBL) that lists IP addresses associated with known spammers or open mail relays. The list is used by email servers to block incoming messages from IP addresses known to be sources of spam.


By checking the IP address of incoming mail against the SORBS database, email administrators can filter out a significant amount of unwanted spam before it reaches the inboxes of their users. However, like any blacklist, SORBS is not perfect, and it is possible for legitimate email to be blocked by mistake. Therefore, email administrators may choose to use other anti-spam measures in addition to checking against SORBS.



Why does your IP gets blacklisted by SORBS?


There are several reasons why an IP address may be blacklisted by SORBS:


Open relay: An open relay is a mail server that allows unauthorized users to send email through it, which can lead to the server being used for sending spam.


Compromised email account: If a user's email account is compromised by a spammer, the spammer can use the account to send large amounts of spam, causing the IP address associated with the account to be blacklisted.


Spoofed email: If a spammer sends email that appears to be from your IP address, even though it was actually sent from another location, your IP address may be blacklisted.


Malware: If a computer on your network is infected with malware, it may be used to send spam without your knowledge, causing your IP address to be blacklisted.


Misconfigured mail server: If your mail server is not properly configured, it may be vulnerable to abuse by spammers, causing your IP address to be blacklisted.


If your IP address has been blacklisted by SORBS, you should take steps to address the issue that caused the blacklisting. This may involve removing malware from your network, securing your email accounts, and properly configuring your mail server. Once you have taken these steps, you can request that your IP address be removed from the blacklist.



How to check if my IP is on the SORBS Spam?


To check if your IP address is on the SORBS Spam list, there are several different methods you can use. 


The easiest way is to use an online service such as Our services allow you to enter your IP address and will quickly tell you whether or not it is listed on the SORBS Spam list.

It is also worth noting that, many email clients (such as Outlook and Gmail) have built-in features that can quickly let you know if your IP address is on any spam lists, including the SORBS Spam list.


Another method for checking if your IP address is on the SORBS Spam list would be to contact SORBS directly and ask them directly whether or not your IP address is listed as a spammer. 


Unfortunately, this direct contact route might be more time-consuming than using one of the online services mentioned above since it would involve more time spent going back and forth with SORBS representatives in order to find out if your IP address has been listed as a spammer by their system. 


However, by going through this process yourself you may be able to gain valuable insight into how their system works and what steps need to be taken once you've identified that your IP address has been blocked by their system.

Removing yourself from the Sorbs Spam Blacklist is a straightforward process. First, you'll need to complete an online form on the Sorbs website, providing your contact details, IP address, and email address.

Once approved by Sorbs, it may take up to 24 hours for your IP address or domain name to be removed from their blacklist. 


It's also important to monitor your domain's reputation on a regular basis to ensure that it remains in good standing with other spam-checking services as well as major Internet service providers (ISPs). A good tip would be to use which can help identify issues related to blacklists and other reputation problems.


You should also consider taking proactive measures such as implementing SPF records and DKIM signatures in order to ensure that your legitimate emails are successfully delivered without being flagged by Sorbs or other anti-spam services.
