+# Deprecated Functions and Code
+
+This document tracks functions that have been marked as deprecated and should be removed in future releases.
+
+## Email Parsing and Processing Functions
+
+### 1. `splitEmailHeadersAndBody`
+- **Location**: `app/courrier/page.tsx`
+- **Reason**: Email parsing has been centralized in `lib/mail-parser-wrapper.ts` and the API endpoint.
+- **Replacement**: Use the `decodeEmail` function from `lib/mail-parser-wrapper.ts` which provides a more comprehensive parsing solution.
+- **Status**: Currently marked with `@deprecated` comment, no usages found.
+
+### 2. `getReplyBody`
+- **Location**: `app/courrier/page.tsx`
+- **Reason**: Should use the `ReplyContent` component directly.
+- **Replacement**: Use `<ReplyContent email={email} type={type} />` directly.
+- **Status**: Currently marked with `@deprecated` comment, no direct usages found.
+
+### 3. `generateEmailPreview`
+- **Location**: `app/courrier/page.tsx`
+- **Reason**: Should use the `EmailPreview` component directly.
+- **Replacement**: Use `<EmailPreview email={email} />` directly.
+- **Status**: Currently marked with `@deprecated` comment, no usages found.
+
+### 4. `cleanHtml` (in server/email-parser.ts)
+- **Location**: `lib/server/email-parser.ts`
+- **Reason**: This functionality has been centralized in `lib/mail-parser-wrapper.ts`.
+- **Replacement**: Use `cleanHtml` from `lib/mail-parser-wrapper.ts`.
+- **Status**: Currently marked with `@deprecated` comment, used in `parseEmail` function.
+
+### 5. `processHtml` (in parse-email/route.ts)
+- **Location**: `app/api/parse-email/route.ts`
+- **Reason**: HTML processing has been centralized in `lib/mail-parser-wrapper.ts`.
+- **Replacement**: Use `cleanHtml` from `lib/mail-parser-wrapper.ts`.
+- **Status**: Currently marked with `@deprecated` comment, still used in the API route.
+
+## Deprecated API Routes
+
+### 1. `app/api/mail/[id]/route.ts`
+- **Status**: Deleted
+- **Replacement**: Use `app/api/courrier/[id]/route.ts` instead.
+
+### 2. `app/api/mail/route.ts`
+- **Status**: Deleted
+- **Replacement**: Use `app/api/courrier/route.ts` instead.
+
+### 3. `app/api/mail/send/route.ts`
+- **Status**: Deleted
+- **Replacement**: Use `app/api/courrier/send/route.ts` instead.
+
+## Migration Plan
+
+### Phase 1: Deprecation (Current)
+- Mark all deprecated functions with `@deprecated` comments
+- Add console warnings to deprecated functions
+- Document alternatives
+
+### Phase 2: Removal (Future)
+- Remove deprecated functions after ensuring no code uses them
+- Ensure proper migration path for any code that might have been using these functions
+- Update documentation to remove references to deprecated code

+# Neah Email Application
+
+A modern email client built with Next.js, featuring email composition, viewing, and management capabilities.
+
+## Email Processing Workflow
+
+The application handles email processing through a centralized workflow:
+
+1. **Email Fetching**: Emails are fetched through the `/api/courrier` endpoints using user credentials stored in the database.
+
+2. **Email Parsing**: Raw email content is parsed using:
+   - Server-side: `simpleParser` from `mailparser` library via `/api/parse-email` API route
+   - Client-side: `decodeEmail` function in `lib/mail-parser-wrapper.ts`
+
+3. **HTML Sanitization**: Email HTML content is sanitized and processed using:
+   - `cleanHtml` function in `lib/mail-parser-wrapper.ts` (centralized implementation)
+   - CSS styles are optionally preserved and scoped to prevent leakage
+
+4. **Email Display**: Sanitized content is rendered in the UI with proper styling and security measures
+
+5. **Email Composition**: The `ComposeEmail` component handles email creation, replying, and forwarding
+   - `initializeForwardedEmail` function prepares forwarded email content
+   - Email is sent through the `/api/courrier/send` endpoint
+
+## Deprecated Functions
+
+Several functions have been marked as deprecated in favor of centralized implementations:
+
+- Check the `DEPRECATED_FUNCTIONS.md` file for a complete list of deprecated functions and their replacements.
+
+## Project Structure
+
+- `/app` - Main application routes and API endpoints
+- `/components` - Reusable React components
+- `/lib` - Utility functions and services
+  - `/services` - Domain-specific services, including email service
+  - `/server` - Server-side utilities
+
+## Dependencies
+
+- Next.js 15
+- React 18
+- ImapFlow for IMAP interactions
+- Mailparser for email parsing
+- Prisma for database interactions
+- Tailwind CSS for styling
+
+## Development

+```bash
+# Install dependencies
+npm install
