In today’s interconnected world, email continues to be a primary mode of communication for businesses. With its ubiquitous use comes the need for secure transmission, and this is where protocols like SMTP (Simple Mail Transfer Protocol) come into play. However, even robust protocols like SMTP are not immune to sophisticated threats. One such emerging vulnerability is SMTP Smuggling — a technique cybercriminals use to bypass email security filters and gain unauthorized access to corporate networks or distribute malicious content.

In this blog post, we’ll take a technical deep dive into SMTP Smuggling, examining how it works, its implications, and ways to mitigate this vulnerability.

Because it validates each DNS query step, network experts frequently refer to it as a chain of trust.
