The 3.0.1.8 update is now available.
We would also like to thank everyone for their support and contributions to this project. 
The following issues have been fixed (hopefully) in 3.0.1.8:
Issue #347 Bug – Missing defines in latest MailWatch
It is recommended that you suspend your mail flow and snapshot prior
to updating or to back up the entire appliance.
1) Stop mail flow temporarily (at firewalls/mailservers)
2) Snapshot your VM and its memory using your hypervisor tools
3) If the update fails for any reason, collect relevant logs or screen
outputs/screenshots and revert to your snapshot
4) Report failure at https://forum.efa-project.org
Launch EFA-Configure from console or secure shell
(sudo /usr/local/sbin/EFA-Configure)
Choose option 14) Update Now
The first time you run this update, the kernel may update. If this
happens, the script will halt to give you an opportunity to restart.
After restarting and booting to the new kernel, rerun EFA-Update to
continue the update process to 3.0.1.8.
EFA-Update will not proceed until you are running on the latest kernel. This is to ensure that open-vm-tools updates appropriately if present.
After updating, please run “Update GeoIP Database” update as soon as possible from MailWatch under Tools/Links.
