There is something in my system that is preventing any user on my Exchange server from receiving emails larger than 5MB. I have been to all of the usual places such as Global/Message Delivery/Default and even in Active Directory under the Exchange General/Delivery Restrictions. My Exchange server is setup to the default 10240KB for both the sending and recieving message size.
I have a SPAM filtering service but I checked the limitation there and it is set to 200MB so that is not the problem. I have no problems sending large attachments it is just receiving them and I can't for the life of me figure out what is preventing me from receiving anything over 5MB.
Here is the non-deliverable message I get when I try to send from outside my Exchange server to an addres on the inside:
