Recently, there has been significant news regarding the SORBS Spam Blacklist service. As of June 2024, SORBS (Spam and Open Relay Blocking System) has officially ceased operations. This means that users and administrators can no longer request the removal of their IP addresses from the blacklist or use the service for email filtering. The closure marks the end of an era for one of the longest-standing spam blacklisting services, which for years played a critical role in email deliverability and security.
In this article, we’ll discuss the impact of this closure and offer alternative solutions for managing email deliverability and spam prevention.
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. Email servers utilize the list to prevent arriving communications from IP addresses recognized as spam sources.
Email managers can filter a lot of unwelcome spam before it gets to the inboxes of their users by verifying the IP address of arriving mail against the SORBS database. Like any blacklist, SORBS is not flawless, hence mistakes could cause legitimate email to be blocked. Email managers may so decide to combine SORBS inspection with other anti-spam techniques.
There are several reasons why an IP address may be blacklisted by SORBS:
An open relay is a mail server whereby illegal users may send emails through it, therefore using the system for spam generation.
Should an attacker compromise a user’s email account, the spammer can utilize the account to send copious of spam, blacklisting the IP address linked with it.
Your IP address may be blacklisted if a spammer emails anything looking to be from your IP address, even though it was really sent from somewhere else.
 Should a computer on your network be compromised with malware be used for spam distribution without your knowledge, your IP address will be blacklisted.
Should your mail server be improperly configured, spammers could be able to access it, banned your IP address could result.
