Problem:
Currently, SMTP2Graph provides minimal logging. Emails can get stuck in the queue for hours, and restarting the service clears the queue, but there is no visibility into what went wrong or what actions were performed.

Proposed Improvements:

Debug Logging:
Enable a debug/verbose mode that logs all actions performed by SMTP2Graph, including underlying tools such as the SMTP server.

Delivery Log:
Provide a log of all delivered or rejected emails with metadata (sender, subject, recipients, timestamp).

Benefit:
Improved logging would simplify troubleshooting, help identify queue issues, and speed up bug diagnosis and resolution.
