Send mail from Linode [Postfix]

Hi Everyone,

This is my first post here although its been a year using a Linode, great environment btw.

So i finally cracked and seen seance I used to run all bells and whistles Postfix for all my mail handling with spamassassan ect too server resource intense so i have switched over and farmed out all my mail to good old uncle Google, best thing i ever done.

I just have the one problem now, i have installed a basic version of Postfix to handle my sending of mail from scripts over to Google which seems to work OK except for when it comes to a .info address.

.net .co.uk .com is fine it just wont send emails out to a .info address, has anyone come across this before?
