Its been a while since I have been here, hope you are all busy.
I have an SBS2008 box running Exchange 2007 using DNS to deliver outbound mail.
I want to switch to our ISP's Smart Host service which I understand is available at smtp.talktalkbusiness.net.
Does anyone have a step-by-step guide for setting this up please. I need to make this switch over later today - hope someone can help.
