We use Exchange 2007 for messaging. One of our administrators has a son with an IPhone. His son sends him pictures that he takes with his phone. His son has a gmail account configured on his IPhone. In the past he has been able to send these pictures and our Exchange server processed them without issue. All of a sudden, within the last couple of weeks he has been getting NDR's stating that the message exceeds the maximum size allowed. Please note: we have already configured the server to have unlimited send and recieve limits. Also the son is not trying to send mutliple pictures, he is only sending one picture at a time. This does not seem like a size limit issue. Below is the NDR message. Let me know if you need more details from NDR. Any help will be appreciated.
