Description: Controls when file-monitor events send emails (e.g., off, high-only, all).

How it works: email_mode decides whether change events are grouped/suppressed or immediately emailed depending on severity and chosen mode.

How to access / configure:

1. WP Admin → AegisShield → File Integrity → Email Settings.
2. Select Email Mode.
3. Save changes and test with a controlled file change.

Recommended setting: Use High-only mode to prevent alert fatigue.
