My Exchange 2007 email environment consists of 2 hub transports, 2 mailbox servers in a CCR cluster and third party spam filter. I am not using Edge transport. I have disabled Content Filter and SenderID filter on the Hub Transport servers. I am receiving random garbled emails from random domains. Here is an example of what I am receiving in the body of the email. I am leaning toward Content-type problem or MIME type. I have enabled a transport rule that has header CONTENT-TYPE value= multipart/mixed. After it was enabled the email came in blank.
Here is an example of the message body:

Can someone please let me know what settings to check or if anyone has experienced this? I have installed Rollup 9 for Exchange 2007 SP1 for all 4 servers and still get the same result
