Hi all. I have an exchange server that has been up and runing now for 90 days no problems. We have not done anything to change anything on the server at all. I have installed SBS 2011 witch has exchange server 2010 as you all know. ok here is the problem. all the suden the emails were being rejected for inbound. And it is hit and miss. you can send an out side email fromme@hotmail.com once, maybe twice and you might get a address rejected. I have ran all updates, Disable the fire wall, ran best pratic, MX recoreds are right, I have even delted MX recoreds and remade them. I get no other errors and like I have said it is hit and miss. some times they come threw other times it wont. any thoughts on what I shouls look at?
