⚙ Full Stack
Python/Flask backend with PostgreSQL, Redis for session/rate-limiting, and a full mail stack (Postfix + DKIM/DMARC/SPF setup) for actually receiving and forwarding email. The mail server component is the real complexity driver — it's not just a web app.
📈 Scaling Analysis
The web app scales normally (stateless Flask behind a load balancer, Postgres + Redis backing). The actual bottleneck is mail infrastructure — DKIM/SPF/reverse-DNS reputation — which is an operational concern no amount of container orchestration solves by itself.
🚀 Running on Nexlayer
Needs app + postgres.pod + redis.pod + a properly configured mail-relay pod with correct DNS (MX, SPF, DKIM) pointed at the deployment. Mail deliverability from a fresh IP is the real-world gotcha, independent of the Nexlayer deploy itself.
