Mail servers play an instrumental role in digital communication infrastructure. The primary role of a mail server is to collect emails from the source and distribute them to the intended recipients. You could consider it an electronic post office that uses different TCP protocols to transfer emails across a network securely and efficiently.

Mail servers receive emails from client computers and distribute them to other servers through the internet. They can also deliver emails from other mail servers to client computers. Kerio Connect is an instant messaging and email server with a wide range of deployment options, web-based access, integration, and mobile service access.

🛠️ How to Set Up Kerio Connect

You can set up Kerio Connect on-premise or opt for hosted Kerio Connect service. Note that the hosted solution cannot be set up in your private infrastructure. Therefore, the guide below will focus on the on-premise setup process for the mail server. Here is how to set up Kerio Connect features step-by-step.

📂 1. Choose The Deployment Type

As aforementioned, Kerio Connect has flexible deployment. It can be installed as a virtual machine, hardware appliance, or software appliance. The versatility of Kerio allows it to run efficiently on various Windows Server installations or Linux distributions.

The software application is ideal for Linux, Mac OS X, and Microsoft Windows. It is also available as a 64-bit virtual appliance, which is highly recommended for modern server environments.

It is also important to note that the functionality is almost similar across the different versions. However, when choosing the deployment type, you have to consider the size of your business. For instance, NG510 is recommended for mid-sized businesses, whereas NG310 is suitable for small businesses that intend to scale. For small businesses, homes, and remote offices, NG110 would work perfectly.

📥 2. Install Kerio Connect

Once you have selected the deployment type, the next step is to install Kerio Connect. The process is pretty simple as all you need is to download the package from the Kerio website. Before starting the download, ensure that your operating system and hardware meet the minimum system requirements.

Download the Kerio Connect installation file, then run the installer. Note that users should do this if they have admin rights to the system. Follow the prompts provided and complete the installation. If there are available updates, you will be prompted through a notification during the process. Always ensure your firewall is configured; you can learn how to configure a firewall to allow mail traffic.

🔑 3. Access The Server

The installation is completed, and the next step is to access the server. The user with the system administrator rights should manage the configuration through a web interface. This can be accessed via a browser using the username and the IP address of the Kerio Connect Server.

The initial configuration will primarily define the administration account, email domain name, software license, and the email data directory. Note that the license registration will take place during this stage. It is crucial to set a strong password for the admin account to prevent unauthorized access.

📁 4. Create And View Public Folders

Note that the public folders can be accessed by multiple users who can share content such as tasks, notes, emails, calendars, and contacts. The default settings are such that the users only have read-only rights. Here you can modify the user settings on the public folders.

For instance, you can assign different users' admin rights to specific public folders such as contacts, notes, etc. The steps are straightforward; you just have to click Accounts > Users in the administration interface.

🌐 5. Configuration Of The Email Domains

Manage email domains by adjusting the various user settings. Note that domains in Kerio Connect make it possible for incoming emails to go to the local mailboxes. For this to work, your DNS server must be correctly pointed to the mail server.

Some of the settings you will manage include password complexity, email footers, directory service authentication, and mailbox retention. To configure email domains, go to Configuration > Domains. Ensure you have a valid domain name registered and active.

🔗 6. Connect To Directory Service

Once the email domains are set up, you can move to connect to the directory service. While Kerio Connect manages users in an open and active directory, administrators don't need to manage the users separately. The user accounts must be connected with the directory service to manage users. This way, user contact information is published in the directory server for easy internal lookup.

👤 7. Create User And Aliases Accounts

Creating user accounts will now make it possible for individuals to access their mailbox. When creating the user accounts, the administrators can manage user rights such as access to certain mail services, mailbox quotas, contact information, and archive folders administration.

The administrator can also create aliases accounts to deliver emails to one or multiple mailboxes. Like the user accounts, the administrator can manage the aliases accounts per domain. This is useful for departments like "Sales" or "Support" where one address reaches multiple people.

📝 Conclusion

Once the user accounts are created, you have finalized the Kerio Connect setup. What would be remaining is managing other server features, such as creating mailing lists and securing Kerio Connect. Mailing lists are created to enhance communication between teams. The general features of the mailing list include posting, subscription, and moderation. For instance, you can create marketing, sales, and support team mailing lists. Every list has several options and capabilities, as mentioned.

You can also modify the Kerio security features to prevent misconduct, identity spoofing, unauthorized access, tampering with information and data, and spammy attachments. Regularly checking for open ports and monitoring traffic is a pro tip for maintaining a secure environment. With the guide above, you should be able to successfully set up Kerio Connect within your mailing infrastructure and enjoy a robust communication platform.
