Email Issues

Operation Baking Gals Northern Ohio is currently having email issues where all Hotmail, some MSN, and some ATT addresses that I am sending to are bouncing back to me, having been marked as spam.
I am trying to resolve what I can, not sure how long it will take. I am receiving YOUR emails, but it is very frustrating to not be able to get a reply to many of you.
Sorry for any inconvenience.
