We have an exchange server in Statistics. One user forwards all his e-mail from the stt.msu.edu domain to his msu.edu account. This works fine except when an e-mail is sent from a few select domains. The ones that repeat themselves consistently are yahoo.com and uiuc.edu. The mail bounces back to the sender with the following error message: Date: Tue, 7 Mar 2006 21:45:22 -0500 From: [log in to unmask] Subject: Delivery Status Notification (Failure) To: [log in to unmask] Body: Open Reporting-MTA: dns;sttweb.sttwin.stt.msu.edu Arrival-Date: Tue, 7 Mar 2006 21:45:22 -0500 Final-Recipient: rfc822;[log in to unmask]: failedStatus: 5.6.1Diagnostic-Code: smtp;554 5.6.1 Body type not supported by Remote HostX-Display-Name: Melfi MSU Date: Tue, 7 Mar 2006 18:43:20 -0800 (PST) From: Xuming He <[log in to unmask]> Subject: RE: Michigan State University To: Dennis Gilliland <[log in to unmask]> Cc: Yimin Xiao <[log in to unmask]>, Vince Melfi <[log in to unmask]> Any ideas?
