Securing Email Communication: Exploring the Evolution and Importance of SMTP in Cybersecurity

Simple Mail Transfer Protocol (SMTP) is a set of rules for sending emails over the internet. Originally developed in the 1980s, it is now the standard protocol for email communication and is used by both Internet Service Providers (ISPs) and private networks to exchange emails. Even in the contemporary era of advanced and encrypted communication pathways, this technology continues to form the backbone of electronic mail transfer system.

SMTP operates at the application layer of the Open Systems Interconnection (OSI) networking model and works closely with the Mail Transfer Agent (MTA) to send your communication from one point to another. It functions with remarkable simplicity, with a classic send-receive model. this strength of simplicity which gives SMTP its name, also makes it notorious in the cybersecurity world.

SMTP's bare-boned protocol structure is both a strength and a vulnerability. While its simplicity enables it to perform its primary function efficiently, it is this very simplicity that makes SMTP susceptible to cyber threats. When not secured adequately,
