Project Summary

Gecko Dynamics developed a verification email service and SMTP API for a telecommunications provider, building an extendable rules engine and message-metadata tracking to ensure security and regulatory compliance. They implemented time-critical components — including an SMTP authentication and charging plug-in developed in C++ — and provisioned scalable Linux/Docker infrastructure. The engagement began in July 2019 and progressed through multiple phases with a small dedicated team.

Key Challenges

Preventing spammers from abusing the platform and ensuring verified email origins.
Building an extendable rules engine adaptable by destination domain and originator.
Tracking message metadata to satisfy transparency requirements and GDPR compliance.
Handling high traffic volume with IP-range management, fast pricing, and fast authentication.
Implementing time-critical SMTP authentication and a charging plug-in compatible with telecom routing.

Project Deliverables

Extendable rules engine
Message metadata tracking system
SMTP authentication and charging plug-in (C++)
Docker-based Linux infrastructure

Project Solution

Gecko Dynamics designed and implemented an extendable rules machine that applies rules and settings by destination domain and message originator, and built a message-metadata tracking system to meet transparency and GDPR requirements. They developed time-critical components — notably SMTP authentication and a charging plug-in implemented in C++ — and provisioned scalable infrastructure using Linux and Docker images. The vendor also supported Java development work and collaborated closely with the client's team using agile practices.

Project Outcome

Phase one completed and the team moved to phase two.
Production readiness was expected by the end of 2019.
Delivered a stable, easily expandable service integrated into the client's infrastructure.
Vendor was responsive, fit into the client's processes, and resolved technical issues quickly (phase one delivered in four months; remaining fix estimated under three weeks).
