I have an exchange server and a W2k server in a DMZ used for SMTP relay. We get the following messages quite frequently. Which bounces the e-mail back to the sender.
Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote Host
I have done some searching on this but have had no luck. I am not seeing anything anywhere that will allow me to change "body types". I am new to Exchange 5.5 and W2k. Does anyone have any idea why I am getting this message and how to correct it?
