Details are everything.. The above should say:

The resolution was to go into:

Exchange Server Management Console
SERVER Configuration (NOT Organization)
Hub Transport
Locate the appropriate Receive Connector
Adjust the value of the Maximum Message Size (KB)

after trying your solutions I found a better workaround.
if you open exchange management shell
do the following:
get-receiveconnector

select the receive connector identity for which you are changing this setting. in servername\identity format

then do the following
set-receiveconnector -identity servername\identity -MaxHeaderSize
128kb (or a higher value)

experiment with this until you do no longer get the error.
to view the current maxheader size:
get-receiveconnector -identity servername\identity |list

cheers,
Marco
