+- **Problem**: Email caching failed when MinIO buckets were set to private
+- **Cause**: Frontend was trying to fetch presigned URLs which failed with CORS/auth issues
+- **Solution**: 
+  - Now reading cached emails directly on server using MinIO client
+  - No presigned URLs needed - server has full authentication
+  - Works perfectly with private buckets
+
+### 16. Email Fetching & Caching Improvements
+- **Optimizations**:
+  - Date-based IMAP search (last 30 days) to reduce email count
+  - Increased timeout from 15s to 30s
+  - Now caching ALL emails (both sent and received)
+  - Fire-and-forget caching to avoid slowing down email fetch
+  - Proper IMAP date format (e.g., "1-Jan-2024")
+

+- **Problem**: EOI dates showing wrong format/timezone
+- **Solution**:
+  - Enhanced date parsing to handle ISO dates, DD-MM-YYYY, and YYYY-MM-DD
+  - Now displays in DD/MM/YYYY HH:mm format
+  - Properly handles timezones
