# Vault Email Processor

This is a Go rewrite of the PHP vault.php script that processes emails for the CMC Sales system.

## Key Changes from PHP Version

1. **No ripmime dependency**: Uses the enmime Go library for MIME parsing instead of external ripmime binary
2. **Better error handling**: Proper error handling and database transactions
3. **Type safety**: Strongly typed Go structures
4. **Modern email parsing**: Uses enmime for robust email parsing

## Features

- Processes emails from vault directory
- Parses email headers and extracts recipients
- Identifies and creates users as needed
- Extracts attachments and email body parts
- Matches document identifiers in subjects (enquiries, invoices, POs, jobs)
- Saves emails with all associations to database
- Moves processed emails to processed directory

## Usage

```bash
go run cmd/vault/main.go \
  --emaildir=/var/www/emails \
  --vaultdir=/var/www/vaultmsgs/new \
  --processeddir=/var/www/vaultmsgs/cur \
