Email communication has become one of the essential parts of communication, especially in the corporate world, allowing the exchange of crucial information and promoting collaboration. However, email has become a popular target for malicious activities, such as spam emails, which can pose significant threats to individuals and organisations. While email providers use machine learning to identify patterns and classify emails, there is room for improvement. This research aims to increase email security by introducing a simple yet effective verification process for three essential email protocols: Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC). By analysing over 500 email headers, we aimed to determine how incorporating these protocols could improve the efficiency of spam detection. Our findings provide valuable insights into the behaviour of Gmail's spam detection algorithms and shed light on the complexities of email header analysis. Through empirical data and theoretical considerations, this research contributes to the ongoing discussion on email security and highlights the potential of protocol verification to strengthen defences against email-based threats.
