Update for BarricadeMX Plus Haraka Engine

This is a minor bug-fix update. The Change Log for the updated version is at the end.

For customers who are using BarricadeMX Plus, the current versions are now:
Package Name Version Number

bmxplus 2.1-10
bmxplus-common 2.1-10
bmxplusd 2.1.10
bmxplus-db 2.1.10
Haraka 2.2.6-2

To upgrade to the latest version of BarricadeMX Plus:

Upgrading BarricadeMX Plus is simple and straightforward. Email delivery should be interrupted only for a very brief period of time during the update process and no messages should be lost, only delayed, by the update. Still it’s a good idea to install the updates at a relatively slow time for email processing. Many sites prefer to install updates after normal business hours.

To update or to see if you need an update for your BarricadeMX or BarricadeMX Plus system(s) simply login as root and run:

yum update

and respond by pressing “y” when prompted.

If you have more than one gateway (a cluster) please update the master gateway first and when the master gateway is finished updating, update the slave gateways one at a time, until all gateways have been updated.

If a “kernel” rpm is installed by the yum update process, please reboot your system(s) as soon as practical so the system will use the new kernel.
And please contact ( to schedule your update if you need assistance with the upgrade installation, have any questions or experience any problems.
