Exchange 2007 Message size exceeds fixed maximum message size

I increased message size to 40MB but when I send a 20MB email I get a 552 552 5.3.4 Message size exceeds fixed maximum message size (state 18). When I do Get-TransportConfig I get the following. Did I miss something?

Hello,

There are multiple places in Exchange where message size limits are sent. In addition to the transportconfig, you need to check your send and receive connectors, your transport servers, and on the mailbox itself. See this article for a good explanation:

I checked that article out already and did everything in it. All the areas are set to 40MB.

The only thing I see is that all the individual mailboxes have sending and receiving check boxes unchecked and empty. Do I need to set them individually? If so, doesn't the global settings take care of that?
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.
