Ubuntu PHP mail() Function with Postfix

php-mail-postfix-ubuntu

# Ubuntu PHP mail
# Ubuntu 12.04 LTS

#  IMPORTANT : add your own data or parameters, I make use of double segments [[ your variable ]]. eg. ssh root@[[ 96.172.44.11 ]] should be replaced with ssh root@888.88.88.88 where "888.88.88.88" is your value, variable etc. I have a habit of using ":::" to indicate line ending and end of paragraph, crazy I know but be warned its just how I write ::: All notes are for my own use & should you use any it's at your own risk, it's NOT a Tutorial :::
