Notifications will not work .....HELP


I had to replace my HD which means a complete replacement of SGP. I had notifications working fine for the longest time. Now, not so much. I am using ATT as my cellphone service and Hotmail as my email service. I have tried all kinds of settings as far as smtp is concerned. All I want to do is get a cellphone text message on an Iphone when something goes wrong . Any help would be greatly appreciated. I followed the instructions in the HELP file and when I try a Test , it fails .

Thanks in Advance,
