v5.3.1 Released • Mailborder

v5.3.1

It has been a while since an update was released, and this is a major update. Most of the focus in this version were updates to the scanning logic, improved detection, and added features to the GUI. AI was leveraged for some improvements and a lot of new language options for the interface.

This release is only available for Ubuntu 22.04 and later due to library requirements. You will need to upgrade your OS using do-release-upgrade until you get to Ubuntu 22.04 before the new Mailborder software will be available to install. The End of Life for Ubuntu 20.04 is April 2025, so it time to upgrade anyway if you are using that OS or earlier.

If you need help upgrading the OS, contact Mailborder support and we will schedule a time to upgrade your server(s). If you have Premium Support, the assistance from Mailborder support to perform the upgrade is included at no additional cost. Otherwise, there will be a fee of $159 to assist in the upgrade.

Changelog

Free 30-day trial licenses are now available during installation. No registration or request required.
Ubuntu 24.04 now supported.
Mailborder now support 42 different languages. Most of them are AI generated. If you see anything incorrect, please let us know.
The interface now supports RTL layouts for the appropriate languages. It isn't perfect, but this feature will continue to be developed. There will likely be a reworked interface in the future will full RTL language support.
DKIM is now configurable in the GUI. It will generate the appropriate DNS entries for you. All you need to do after that is make the required DNS records.
SPF checking is now configurable in the GUI.
The latest repository install script has been updated to confirm with the newer standards in Ubuntu. This will make future upgrade from one release to another much more streamlined.

Debian control packages updated to make release upgrades easier.
GeoIP database will now be updated daily from the Mailborder update servers.
A new malware and phishing update infrastructure is now in place on the Mailborder update servers. Mailborder servers now pull these updates every few hours.

The command mb-trace has been added to trace an email through all syslog files. This is the same executable used to update the delivery status in the GUI.
