Summary of Steps:
- Install a supported operating system
- Setup DNS Requirements
- Run the repository installation script
- Install via the system package manager
- Create a Mailborder account on this website
- Obtain a Mailborder license code via the store
Supported Operating Systems
The following operating systems are supported by Mailborder. Any variant of these operating systems will also work. For example, Elementary OS Juno is based on Ubuntu 18.04 LTS. Therefore, it may be used with Mailborder.
| Operating System | Version/Release |
| Ubuntu 20.04 LTS (preferred) | Focal 64 bit |
| Ubuntu 18.04 LTS (master only) | Bioic 64 bit |
*There are no plans to support Red Hat or CentOS.
DNS Requirements
Mailborder v5 uses FQDNs to access the Master server interface and for communication between Master and Child servers. It is critical DNS is setup before installing the software. The Master interface is not accessible via IP address.

Recommended Hardware
Hardware requirements are going to vary depending on email volume, quarantine retention, and archive retention. You may use physical or virtual servers. The more database inserts on the Master server and the heavier the use of the User Portal will determine your CPU requirements for a smooth experience. Child servers not only provide high availability, but they also relieve the Master server of the heavy load of processing email. Below are some recommendations:
Master and Child Servers
| CPU Cores | RAM | HDD | |
| Minimum | 2 | 4GB | 60GB |
| Recommended | 4 | 8GB | 120GB |
| Heavy Use | 8 | 16-64GB | 240-400GB |
Licensing
To help you find the model you need, see our complete Master Server Capability Matrix and the license calculation guide. Then select your server license from the Mailborder store. Trial licenses are available.
Adding the Mailborder Repository
Mailborder is installed via your server’s package manager apt (Debian/Ubuntu). Our repository must first be added to your server’s configuration. As the root user or via sudo, use the setup script to add the Mailborder repository:
cd /tmp wget https://s3.amazonaws.com/mbv5/core/install_deb_repo.sh chmod +x install_deb_repo.sh sudo ./install_deb_repo.sh
Master Installation
Run this command to install the Master software:
sudo apt-get install mailborder-master
Follow the remaining directions within the setup program. Ensure that the server is rebooted once the installation is complete.
* When asked about the configuration type for Postfix, select “No Configuration“.
Child Installation
The installation steps for the Child server are the same as the Master server. However, you will need to add the Child server to the Master server’s cluster first.
Master Server GUI Menu > Cluster > Member Servers > Add
Again, the DNS Requirements must be met prior to installing the software. Run this command to install the Child software:
sudo apt-get install mailborder-child
Follow the remaining directions within the setup program.
* When asked about the configuration type for Postfix, select “No Configuration“.
Migrating a v4 to v5 Master Server
You can migrate some of your configuration data from v4 to v5. This includes domains, networks, email forwards, white lists, and black lists. For more information see How to Migrate v4 data to v5.
