# Email System Fixes

## Issues Addressed

### 1. Email Credentials Not Found Errors
- **Problem**: The system was trying to fetch emails even when no credentials were present
- **Solution**: 
  - Added session ID check in `EmailThreadView` before attempting to fetch emails
  - Modified `fetch-thread` API to return empty results instead of throwing errors when credentials are missing
  - Added proper session cleanup in `EmailCommunication` component

### 2. 502 Gateway Timeout Errors
- **Problem**: Email fetching was causing timeouts, especially when editing/saving interest cards
- **Solution**:
  - Reduced email fetch limit from 50 to 20 emails
  - Added 15-second timeout for IMAP connections
  - Prevented unnecessary email fetches when no session exists

### 3. EOI Generation Issues
- **Problem**: EOI generation may fail due to missing Documenso configuration
- **Solution**:
  - Added environment variable validation for `NUXT_DOCUMENSO_API_KEY` and `NUXT_DOCUMENSO_BASE_URL`
  - Improved error messages to indicate when configuration is missing

## Required Environment Variables

Make sure these are set in your `.env` file:

```env
# Email Configuration
NUXT_EMAIL_ENCRYPTION_KEY=your-32-character-encryption-key
NUXT_EMAIL_IMAP_HOST=mail.portnimara.com
NUXT_EMAIL_IMAP_PORT=993
NUXT_EMAIL_SMTP_HOST=mail.portnimara.com
NUXT_EMAIL_SMTP_PORT=587
NUXT_EMAIL_LOGO_URL=https://portnimara.com/logo.png

# Documenso Configuration (REQUIRED for EOI generation)
NUXT_DOCUMENSO_API_KEY=your-actual-api-key
NUXT_DOCUMENSO_BASE_URL=https://signatures.portnimara.dev
```

## How It Works Now

1. **Email Session Management**:
   - Sessions are stored in browser's sessionStorage
   - If no session exists, email features are gracefully disabled
   - Users can connect/disconnect at any time

2. **Email Fetching**:
   - Only attempts to fetch when valid session exists
   - Limited to 20 emails to prevent timeouts
   - Falls back to cached emails from MinIO if IMAP fails
   - 15-second timeout prevents hanging connections

3. **EOI Generation**:
   - Validates all required fields before attempting generation
   - Checks for Documenso configuration
   - Returns clear error messages if configuration is missing
   - Inserts client's signing link directly into email body

## Troubleshooting

If you're still experiencing issues:

1. **Check Docker logs**: `docker logs <container-name>`
2. **Verify environment variables are set correctly**
3. **Ensure Documenso API credentials are valid**
4. **Try disconnecting and reconnecting email credentials**
