“SORBS has a long and storied history. It was created in the early 2000s, with a version of the DNSBL (Domain Name System-based Blackhole List) coming online in January 2002,” Chandler wrote. “The shutdown of SORBS does not mark any real change in email security. Although it was one of DNSBL’s older services, SORBS mainly helped email administrators who were interested in filtering spam and other malicious email traffic. However, its controversial history and management issues have made it a source of frustration for many in the industry and stifled its overall use. SORBS listings have not been considered influential in the email marketing space for many years. A recent customer saw less than 200 messages blocked with a volume of less than a million.”
Other ways to filter spam
Girish Bhat, a security marketing executive who worked for Proofpoint when SORBS was acquired, said the decisions were influenced by business dynamics and the difficulty of making such an inventory profitable.
“For a fast-growing business like Proofpoint, monetization would have required a large investment, and the ROI was unclear. I believe the email industry would not have reached this point without DNSBL services such as Spamhaus, SpamCop, SORBS and others. As most of these services were started by a dedicated person or people with strong opinions, said Bhat. “Shockingly, even after the purchase of SORBS, it did not interfere with its daily operations. Although SORBS was quickly abandoned it was a pioneer and played an important role in society in the past, its use has declined due to the abundance of other services.”
