DevOps Specialist: Postfix Multi-IP /24 Subnet Routing & Mautic Deployment (Ubuntu 22.04 LTS)

@rupa37

Leveraging over 15 years of solid experience in DevOps and system administration, I, Rupa, offer the deep proficiency and broad skillset you need to successfully complete your project. My core expertise includes, but is not limited to, creating and managing large-scale multi-IP Postfix transport maps and tuning high-write databases for optimal performance. I'm intimately familiar with Linux distributions, especially Ubuntu 22.04 LTS, having worked extensively with them throughout my career. Adding to my Linux experience is a proficiency in network administration backed by a strong Cisco networking solution understanding. This will be valuable in configuring the /24 subnet block and handling its routing through proper mappings and aliases. Additionally, my skills extend to implementing automated log parsing with Elastic/Filebeat structures – a requirement you've specified for this project.

Hi, I have 15+ years of experience in Linux, email infrastructure, high-volume SMTP platforms, DevOps, and network engineering. I can help design and deploy the complete Ubuntu 22.04 mail infrastructure, including: • Ubuntu hardening, kernel tuning, BBR, and system optimization • /24 subnet configuration and IP aliasing • Postfix multi-IP transport configuration and sender-dependent routing • OpenDKIM, SPF, PTR/rDNS validation, and mail deliverability best practices • Mautic deployment on an optimized Nginx/PHP-FPM/MariaDB stack • Filebeat log parsing and webhook-based event streaming • Monitoring, documentation, and infrastructure handover Relevant experience includes large-scale Postfix deployments, Linux performance tuning, mail delivery infrastructure, automation, and observability pipelines. My focus is on delivering a stable, scalable, and fully documented platform that meets your acceptance criteria while maintaining clean operational practices. Available to start immediately and comfortable working within your 7+2 day execution window and NDA requirements. Rahul

I understand that you're looking to establish a robust and high-throughput mail transport solution using a dedicated Ubuntu 22.04 LTS instance, while efficiently managing your /24 subnet with Postfix and Mautic at the core. Ensuring optimal performance and security is crucial in this setup. With 12+ years of experience in DevOps and infrastructure management, I have successfully implemented multi-IP Postfix transport maps and optimized high-write databases for Mautic deployments. My expertise also includes configuring Netplan for IP aliasing, hardening Ubuntu systems, and setting up telemetry using Filebeat for effective log streaming. I can ensure that the milestones are met, from successful host provisioning to verifying the technical setup score on Mail-Tester. Could you please clarify if there are specific performance metrics or benchmarks you aim to achieve during the testing phase?

With over 5 years of experience in DevOps and Infrastructure Engineering, I specialize in the implementation of open-source stacks. I can configure Netplan for your /24 subnet, optimize kernel settings, and set up the Postfix Multi-IP VirtualMTA to ensure efficient mail distribution. My background includes deploying optimized LEMP stacks for applications like Mautic and configuring Filebeat for real-time log streaming. I’m capable of delivering the technical setup score you require. I’m looking forward to discussing how we can move forward.

As a seasoned DevOps specialist familiar with the intricacies of network administration and Linux, I have developed and maintained numerous high-throughput mail transport layers. Combining this expertise with my deep understanding of open-source Postfix and Mautic architecture, I’m confident in being able to harden, provision, and configure a cutting-edge Ubuntu 22.04 LTS instance that perfectly fits your project description. Let’s dive into some relevant areas of my experience: Firstly, I am well-versed in OS hardening and network configuration - two cornerstones of this project. Not only can I cleanly map your entire /24 subnet block on Netplan/local interfaces but also adept at strengthening Ubuntu's kernel for optimal performance by employing BBR congestion control and lifting file-descriptor limits where necessary. Secondly, regarding Postfix Multi-IP VirtualMTA Setup and Mautic Application Provisioning – two critical components - I've consistently proven skilled at achieving sender-dependent default transport maps for efficient outbound mail distribution across vast IP footprints. Importantly, my deft hand at deploying hardened LEMP stacks for performance-intensive applications is another asset you can rely on.

Hello, I am interested in assisting with this project. I have experience with Ubuntu server administration, Postfix mail infrastructure, Linux networking, Mautic deployments, database optimization, and Filebeat log processing. I can: • Harden and optimize Ubuntu 22.04 for high-throughput workloads. • Configure Postfix multi-IP outbound routing, DKIM, SPF, and rDNS. • Deploy and optimize a production-grade LEMP stack for Mautic. • Implement Filebeat log streaming to your webhook endpoint. • Tune kernel, BBR, network settings, SMTP queues, and system limits. • Provide deployment documentation and support during the validation phase. I am comfortable working under NDA and can follow the 7+2 day deployment lifecycle. I would be happy to discuss your infrastructure requirements and implementation approach in detail.
