Horde & Zimbra Video Tutorial

I need a clear, narrated video that walks step-by-step through installing and fully configuring both Horde Groupware and Zimbra Collaboration on a fresh Linux server. Start with the prerequisites (system update, hostname, DNS, firewall ports, required packages) and then show the full installation process for each platform, including repository setup, package download, and service start-up.

Once installed, move straight into configuration: create the first admin account, set up domains, mailboxes, SSL/TLS, and demonstrate sending and receiving a test message in each environment. Please explain every command on screen, highlight key files that are edited, and point out common pitfalls so viewers can reproduce the build without guesswork.

Deliverables
• HD screencast (1080p or better) with voice-over, broken into logical chapters for easy navigation
• A simple text file listing every terminal command and configuration path used in the video

I will consider the project finished when I can replay the tutorial, follow along, and end up with two fully functioning, externally reachable mail systems—one running Horde, the other Zimbra—without additional guidance.
