What is the default setting for removing English email signatures and footers for new indexes?

The correct answer indicates that the default setting for removing English email signatures and footers for new indexes is "Yes." This means that when a new index is created, the system is configured by default to eliminate English email signatures and footers from the data being indexed. This functionality is essential in data processing, especially for legal or compliance purposes, as it helps to ensure that irrelevant or non-essential information does not clutter the indexed content.

The removal of such signatures and footers is beneficial for enhancing the quality and relevance of the data being analyzed. It helps to focus on the core content of the emails without extraneous information that does not contribute to the understanding of the email's primary message.

In contrast, the other choices imply either a neutral stance, selectiveness based on specific conditions, or variability based on the type of index, which does not align with the standard practice reflected in the selected answer. The default setting is designed for efficiency and clarity, ensuring that users can access only the critical information needed for analysis and decision-making, thereby streamlining the index creation process.
