    I followed The Perfect Server - CentOS 6.4 x86_64 (Apache2, Dovecot, ISPConfig 3) guide for this.

    Wow, just wow.

    I've just discovered that the "Perfect Server" guide is more like the "Broken Server" guide.

    After enough research I was able to fix this with a couple of simple symlinks that were NOT mentioned in the tutorial.

    Please update tutorial or there will be many more topics about this in the near future!
