Could you build this?

Partial The frontend dashboard and API assertions are simple to vibe-code, but hosting dedicated inbound SMTP capture servers with custom DNS subdomains and email parsing requires robust mail infrastructure.

What it would actually take: The service needs a custom SMTP receiver (e.g., built with Go, Haraka, or Stalwart) bound to public MX records to intercept, parse MIME messages, extract attachments, and validate SPF/DKIM/DMARC headers. Messages are indexed in a message queue (Kafka/RabbitMQ) and Redis/PostgreSQL for real-time WebSocket delivery and SDK polling. Reliable mail-server infrastructure operations and deep knowledge of email RFCs are required.
