DevOps Engineer: Minimalist Linux Mail Transport (MTA) & Netplan /28 Subnet Routing
Budget: $30 – $250 USD
Project Description:
We are seeking an agile, highly disciplined DevOps engineer to execute a clean, streamlined mail infrastructure deployment on a freshly provisioned bare-metal Linux environment. This is a highly focused task requiring technical precision under a lean, execution-focused framework.
Technical Scope of Work:
• OS & Kernel Optimization: Perform initial hardening on a clean Ubuntu 22.04 LTS minimal net-install. Activate kernel BBR congestion control and optimize system file descriptors (nofile limits up to 65535) to handle concurrent high-volume outbound threads.
• Network & Subnet Mapping: Configure a routed, contiguous /28 IPv4 network block via Netplan. Statically alias the usable IP footprint sequentially to align with our predefined enterprise reverse DNS (rDNS/PTR) naming architecture (ranging from s1 through s14).
• MTA & Open-Source Application Stack: Deploy a highly optimized, headless outbound mail transport agent (Postfix) utilizing sender-dependent default transport maps. Bind this transport layer to a standard, open-source open-source marketing automation application base layer running over a hardened LEMP stack.
• Telemetry & Logging: Ensure local log-shipping utility configurations are prepared to parse mail transport logs in real time and stream performance metrics to a centralized external JSON webhook payload endpoint.
Project Governance & Terms:
• 2-Milestone Delivery Framework: To maintain absolute operational efficiency and prevent escrow fragmentation, this project operates strictly under a consolidated 2-stage milestone matrix (Milestone 1: Core Base Environment Layer; Milestone 2: Subnet Transport Routing, Telemetry, & Handoff).
• Strict Timeline: This sprint is bound to a strict 7-day active development cycle followed by a 2-day monitored window for global DNS propagation and final verification (Passing a perfect 10/10 score on external validation tools).
• Compliance & Mutual NDA: The selected contractor will be required to provide their full legal name and execute a standard Mutual Non-Disclosure & IP Assignment Agreement within the workspace chat before server root credentials or backend API schemas are released.
