mailCow has emerged as a valuable resource in my arsenal of server management tools, offering me a comprehensive and reliable solution for email management on my domains.
Implemented on Ubuntu as a VM within my Proxmox environment, mailCow provided an excellent platform to better understand the complex mechanisms of DNS, email protocols, and network configurations.

Utility and Advantages: mailCow has proven to be an essential tool for managing free and reliable emails for my domains. Thanks to its intuitive interface and powerful features, I can easily manage email communications without needing expensive third-party solutions.

This included installing Ubuntu 22 as a VM on Proxmox, checking and configuring the firewall and ports, and correctly synchronizing the system’s date and time.
DNS Configuration: To ensure proper functionality of mailCow, I carefully configured my domain’s DNS records on CloudFlare following the instructions provided in the mailCow guide.
Installation and Configuration: Using the curl command available on the official mailCow website, I downloaded and installed the necessary software. Subsequently, I enabled and installed Docker and Docker Compose and completed the configuration process via the provided docker-compose.yml file.

Conclusions: Thanks to the implementation of mailCow, I gained a deeper understanding of email management mechanisms and associated network protocols. Its ease of use and reliability have made mailCow an indispensable resource in my server management tool arsenal, significantly improving my system administration experience.
