About a week ago, my Exchange server stopped receiving mail from outside addresses. I can send / receive within my own network and I am able send to outside addresses. OWA works fine from work and home as well. However, when I try to email work from an outside address I get a Delay and Failure Notifications. So to make a long story short, we're not getting anything more than interoffice e-mail here.
, it tells me:
"ERROR: I could not connect to any of your mailservers! Connection closed before I received all my data (state 1)."
