# This script is just to help streamline the         #
# install process for Debian and CentOS              #
# based distributions. I assume you will be          #
# installing as a subdomain on a fresh OS install.   #
# Right now I'm not going to worry about SMTP setup  #

# Feel free to modify, but please give               #
