Exchange 2003 sending messages with BAD HEADER and MIME ERRORs

I am really hoping someone can help me  track down the cause of email messages arriving without anything in the message body. The subject lines are filled in but the  message body is blank.  We have a handful of users who are intermittently experiencing the problem. Most of the time things work fine but occasionally they send something and it arrives with blank messages.

We are running Exchange 2003, SP2 on Windows 2003 SP1. The clients are MS OUtlook 2003 SP2. We recently went to the Office Updates website and ran all updates on the client but the problem persists.

Our network engineers have looked into it and they say "something between your clients and your mail server is mishandling or even truncating messages."

Here is an example of errors found by using GREP:

Feb 26 08:42:08 sr-6-int amavis[20187]: (20187-19) BAD HEADER from <>: MIME error: error: part did not end with expected boundary

The engineers mentioned that BAD HEADERS can happen if the system is trying to squeeze 8 bits into a 7 bit format. I found the following info on Google:

 "Email, however, is a 7-bit (or text) medium, preventing the transfer of 8-bit data. UUencoding compensates for this restriction by converting 8-bit data to 7-bit data. UUencode accomplishes this by joining all of the file's bits together into a single stream, and then dividing the stream into 7-bit chunks. ..."

Although we may be closing in on the cause of the problem, I still don't know how to fix it. This is an urgent issue because our director is the one who is experiencing the most frequent problems with this and it has been going on for a few weeks. Any help in tracking this down and fixing this would be greatly appreciated!
