Mailborder Email Gateways

Purpose
Mailborder spam and virus filter gateways are servers that are deployed between the internet and your internal email servers. Alternatively, they can also be used to protect hosted email services such as Office 365, Kerio, or Zentyal.

Capability
Mailborder filters inbound or outbound email for spam, viruses, malware, ransomware and a host of other checks. They have graphical web interfaces, so being a Linux expert is not required.

Compatibility 
Our solution can protect any email server platform against external threats. It will also work with any email service that allows transport management. Most do, but if you are unsure, contact us.

Deployment
Your Mailborder server can be physical or virtual. You can use your own data center or have your Mailborder server hosted by any popular provider such as Amazon Web Services, Digital Ocean, or Linode.

Clusters
Mailborder servers are cluster capable for high availability. Instead of just one server, you can run a high availability cluster of one Master server with one or more Child servers in the same or remote locations.

Your Network. 100% Control.

For maximum granular control, choose the Mailborder Email Gateway in your own data center.

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 SystemVersion/Release
Ubuntu 18.04 LTS (preferred)Bionic
Ubuntu 16.04 LTSXenial

More operating systems will be added at a later date, such as Debian 10 Buster when it becomes available.

 

Red Hat Notes

Mailborder makes extensive use of PHP 7.x, which is not yet supported by Red Hat. Also, Red Hat also does not include numerous other packages used by Mailborder in its repository.

Performance

  • Mailborder v5's database is over 50x faster than v4. Yes, 50x.
  • The v5 email scanning engine is over 12x faster than v4.
  • A single 4GB Child server can process over 1,000,000 emails in 24 hours.
  • v5 Child servers can run without the Master indefinitely during an outage.

Flexible Design and Deployment

High availability built right in.

Child Servers

Child servers extend the cluster's spam and virus filtering to additional servers. They expand with the Master server license, so there is no need ever to purchase license upgrades for Child servers. They will continue to function without the Master server in the event of a communication failure.

They do not need to be directly configured once connected to the cluster. Communication between Mailborder servers is via standard HTTPS connections.

User Portal

An optional feature for the Master server is the User Portal. It allows user access to view or manage rules for their own email.

Group Administrators can also be assigned, which allows these types of users to see and manage all of the email within their group. Groups may contains multiple domains.

When you are ready, start your installation with this guide.

 

Licensing

Mailborder licenses scale on objects. Objects are items that are controlled by defined policies. User email address are not objects as they fall under things like Domains and Networks. For a complete overview, see our license calculation guide.

Recommended Hardware

Hardware requirements are going to vary depending on email volume, quarantine retention, and archive retention. 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.
