Describe The Request Create a new script that is able to assist with SMTP protocol logging review.

Key points to included:

  • Generic review of the log to find any issues like sessions being started but never used
  • Following a single message from start to finish hopping between servers
    • Call out possible logs missing for full review
  • Call out large time gaps between entries - Example: BDAT sending 700 bytes the next entry is a session closed 5 minutes later.
  • Able to run on Exchange - Made easier to hop between servers following a message due to EMS

Research direction
Examine existing log parsing tools in the repository. Understand the format of Exchange SMTP protocol logs (typically text files). Create a script that can scan logs for anomalies like abandoned sessions, track message flow across multiple servers, and detect large time gaps. Consider adding options for reporting and exporting results.
