iRedAdmin

I am new to iRedMail and iRedAdmin. I am planning to install iRedMail in my new VPS, as per the following tutorial (URL).

https://www.digitalocean.com/community/ … -12-10-x64

I have a few questions:

1. Is iRedAdmin a web hosting control panel like cPanel and VirtualMin ? Or is it just an email Admin tool for using with iRedMail ?

2. Is the iRedAdmin specified in the above tutorial (URL), a GPLv2 version of iRedAdmin ? I mean, will it install the GPLv2 version or the Commercial Paid Version (iRedAdmin-Pro) ?

3. What is the License of iRedAdmin-Pro ? Is it GPL ?

Please help.

Thanks.
