Could you build this?
Partial The API and web UI for viewing received emails can be vibe coded, but configuring and managing a reliable custom MX mail server infrastructure that reliably parses incoming SMTP traffic requires dedicated infra setup.
What it would actually take: A production version requires an incoming SMTP server daemon (using Postfix, Haraka, or a custom Go/Rust SMTP listener) tied to public MX DNS records. When an email is received, it must be parsed (MIME, multipart, attachments), securely isolated, and published via message queues (e.g., RabbitMQ or Kafka) to an API backend with WebSocket support for real-time browser notifications. The hard parts are maintaining SMTP reliability, parsing arbitrary malformed email formats, and handling abuse prevention/spam filtering while ensuring high throughput during automated testing spikes.
