I havent recieved the script, streamline automatically set up ten e-mail addresses for you so you can have eg
support@yourdomain.co.uk,
contact@yourdomain.co.uk etc, etc the yourdomain.co.uk bit would obviously change to the domain name you registered eg
support@dap-webdesign.co.uk
when you are on the linux server I dont think you will need to add the extra line of code.
