How to install squirrelmail on Blueonyx 6 version 5107R (CentOS 6)

I'm sure many of you have now figured out that webmail is not included in the current 5107R (version 6) of BlueOnyx.
This should also work for installs of CentOS 6 but no testing has been done for this.
If you want to install it, it is a fairly simple process:

1:Install the EPEL repository

SSH into your server and su to root.
Install the EPEL repository with this command:
yum install epel-release
DO NOT RUN YUM UPDATE!!! doing so at this point will mess up your server!!

2:Install Squirrelmail

Install squirrelmail with these commands:
yum install squirrelmail.noarch
Allow it to intall dependencies, but it is very important that you do not attempt to install anything else.
you should get an output something like this:
Resolving Dependencies
--> Running transaction check
---> Package squirrelmail.noarch 0:1.4.22-4.el6 will be installed
--> Processing Dependency: php-pear-DB for package: squirrelmail-1.4.22-4.el6.noarch
--> Running transaction check
---> Package php-pear-DB.noarch 0:1.7.13-3.el6 will be installed
--> Finished Dependency Resolution

3: Remove the EPEL repository

Search for the RPM name with this: rpm -qa |grep -i epel
Remove the EPEL RPM with this:
yum remove epel-release
DO NOT forget to remove the EPEL or the next auto-update will mess up your server.

4: Install the BlueOnyx addons

Use these commands to install the remaining files:
You need to wget these files:
wget https://www.server-centre.net/support/files/blueonyx-squirrelmail.zip
Extract the files with: unzip blueonyx-squirrelmail.zip Then install with:
yum install base*

5: Reconstruct CCE and restart the Admin server

Reconstruct the CCE with this: /etc/init.d/cced.init restart
Restart the Admin Server with this: /etc/init.d/admserv restart
If all has gone well, you should now be able to access webmail with the following url:
http://IPADDRESS:444/webmail/

It is EXTREMELY important that you do not run yum update with the EPEL installed as it WILL damage your system.
Make sure the EPEL is removed BEFORE trying to update.
