FEATURED INFRASTRUCTURE PROJECT

LiveInbox — Email Deliverability & SMTP Handshake Engine

A high-precision mailbox verification system built in Go. Direct SMTP negotiation confirms mailbox existence without dispatching test emails, protecting domain sender scores.

DEPLOYMENT

INTERACTIVE SMTP PROBER

SIMULATOR

Test the 4-stage verification chain implemented in Go: DNS MX query, token rate-limiting, raw SMTP socket handshake, and deliverability risk scoring.

1. Syntax

2. DNS MX

3. Handshake

4. Verdict

INIT: Probing MX records for 'divinopastor.com.ar'...

DNS: Found primary MX 'aspmx.l.google.com' (priority 1)

NET: Negotiating low-level SMTP TLS handshake on port 25...

HELO: mail.liveinbox.engine -> 250-aspmx.l.google.com

RCPT TO: <julieta.marino@divinopastor.com.ar> -> 250 2.1.5 OK (Mailbox exists)

VERDICT: Status = VALID | Category = LIVE | Catch-All = NO | SPF = PRESENT

Go concurrency & rate-limiting safe for remote mail daemons

Zero emails transmitted during mailbox availability verification

Architecture & Core Implementation

Custom SMTP protocol engine written in Go executing non-intrusive RCPT TO handshakes.
DNS MX routing inspection and DNS cache layer with catch-all and disposable domain heuristic classification.
Token-bucket rate-limiting algorithm preventing IP throttling and reputation degradation across remote mail exchanges.
Clean REST API layer built using Go's chi router, PostgreSQL persistence, Redis queue/caching, and Docker Compose orchestration.

TECHNICAL CAPABILITY SIGNALS

Core Engineering Competencies

Key areas of practical execution: low-level network protocols, systems diagnostics, and resilient infrastructure.

Go / Concurrency

Go & High-Concurrency Systems

Raw socket connections, custom SMTP state machines, chi REST APIs, and goroutine pools.

Authorized Testing

Defensive Security & Audits

Scoped network enumeration, service reconnaissance (Nmap, Hydra), and permissioned credential resilience testing.

Postgres / Redis

Data Persistence & Queuing

PostgreSQL schemas, Redis fast-caching & job queues, and connection pool diagnostic utilities.

Docker / Linux

Containerized DevOps

Docker & docker-compose service stacks, Nginx reverse proxying, Linux systemd orchestration on DigitalOcean.
