Operating System: Windows Server 2012 and newer, or Windows 10 / 11 for testing.
RAM: Minimum 1 GB (2 GB or more recommended for active servers).
Storage: Depends entirely on your email volume and retention policies. Prerequisites: .NET Framework 3.5 or higher. Step-by-Step Installation Guide
Once you have downloaded the installer, follow these steps to get your mail server up and running: Step 1: Run the Installer
Double-click the downloaded executable file. Accept the license agreement and choose your installation directory. Step 2: Choose Components
You will be asked to choose between a "Full installation" or "Custom installation." For most users, a full installation—which includes both the Server and the Administrative GUI—is the best choice. Step 3: Select Database Type download hmailserver 57 hot
hMailServer needs a database to store its configuration and account data.
Built-in Database: Best for small setups or testing (uses Microsoft SQL Server Compact).
External Database: Best for production environments. You can connect it to an existing MySQL, PostgreSQL, or Microsoft SQL Server. Step 4: Set the Master Password
During the installation, you will be prompted to create a master password. Do not lose this password. You will need it every time you open the hMailServer Administrator tool to make changes. Basic Post-Installation Configuration
After completing the installation wizard, open the hMailServer Administrator to complete the setup. 1. Add Your Domain
Click on Domains -> Add... and type in your domain name (e.g., yourdomain.com). Click Save. 2. Create Email Accounts
Navigate to your new domain, click on Accounts, and click Add... to create user mailboxes. Enter the username, set a secure password, and click Save. 3. Configure DNS Records
For your email server to send and receive mail properly across the internet, you must configure your external DNS settings:
MX Record: Points to the IP address or hostname of your hMailServer.
A Record: Maps your mail subdomain (like yourdomain.com) to your server's static IP.
PTR Record: Crucial for reverse DNS lookup to prevent your emails from being marked as spam. Best Practices for Security
Running your own mail server requires diligence to prevent spam abuse and hacking attempts.
Enable SSL/TLS: Never send passwords or emails in plain text. Generate an SSL certificate (you can use free Let's Encrypt certificates) and bind it to your SMTP, IMAP, and POP3 ports.
Set Up DKIM and SPF: These DNS frameworks prove to other mail servers that emails originating from your server are legitimate.
Utilize the Auto-Ban Feature: Enable auto-ban in the hMailServer settings to block IP addresses that fail to login after a certain number of attempts.

Will this be for production use or a local testing environment?
Do you plan to use the built-in database or connect to an external database like MySQL?
