Issue/Introduction

Symantec Messaging Gateway (SMG) is unable to detect some content filtering conditions when the text that would match the configured condition is part of an attached Excel document.

For example, a content compliance rule which attempted to match the "Credit Card Number Keyword" dictionary keywords might not fire in some cases when the matching text is part of a Microsoft Excel attachment depending on how the data was stored in the Excel file.

Cause

This is a combination of how some Microsoft Excel files store data internally and how that data is processed internally by SMG.

Resolution

This issue has been addressed in Symantec Messaging Gateway version 10.0.1-2.
