This script i have created to create qmail user using space separated file.
File format i have received is <user> <account / forward> <forward> <forward> <forward> <forward> <forward> <forward>
but the forwarder was not fixed.

#!/usr/local/bin/bash

Following is script does not work.
but will fix it shortly.
