Is possible to stop Exchange 2007 Sp1 from removing internet headers and routeing information from messages forwarded as attachment? I need to retain those as they contain crucial spam reporting information. Why does Exchange remove these by the way?

Hello Hapklaar, I test the following steps in my side: I create a new message and add an attachment which is a mail sent from external, then send it to myself, check it in my Outlook, the header information is complete and never be modified. If there is something misunderstood, please let me know. The behavior you described is abnormal. Is there any third party software in your server? Thanks, Elvis

Hello Elvis, Thank you for your reply. A customer forwarded me some spam in which the routing and spam info was completely missing, also internal routing, so I assumed Exchange had done this. But as you say when I test this myself with other mail that info is not stripped. I actually have no clue how that spam could be missing it's routing information. Anyway, Exchange does not seem to be the problem here I guess so I'll mark this as answered.. Thanks again Erwin PS Don't know if anyone knows what could be the problem here, but some mail is actually stripped of headers. Here is an example of the complete header of a forwarded (as attachment) message: Content-Class: urn:content-classes:message MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----_=_NextPart_008_01C9C0AF.7CA88B00" X-MimeOLE: Produced By Microsoft Exchange V6.5 Subject: boost your sweet bed times Date: Sun, 19 Apr 2009 07:27:07 +0200 Message-ID: <000d01c9c0af$7b479b70$6400a8c0@sierrazkdq1> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: boost your sweet bed times Thread-Index: AcnAr3/K9H2/iNwnS9aGArzsVFxPSg== From: "Orville Britton" <sierrazkdq1@thedoctorsoffice.ws> To: "xxxx" <xxx@xxxx.nl>

Hello, This is indeed not a problem with Exchange. It will always modify and stamp new headers on a forwarded message (depending upon the situation). If you want to retain the header information on any of the mails you may want to ask your customers to forward those emails as an attachment in stead of fowarding them in a normal way.

The messages in question were forwarded as attachment like I stated in my post.

This can also be a spoofed message. I have seen many cases where headers information is missing in spoofed messages. Spoofed messages can also get generated within your own network on sometimes on your mailbox.MMilind Naphade | MCTS:M | http://www.msexchangegeek.com

Hello Erwin,Please check the third party software to see if they stripped the header information. As a workaround, you could suggest the sender to save the emails you want into a pst file, zip the pst and then send to you. Regards,Elvis

I have not been able to reproduce this effect when I tried to forward the spam myself. Exchange does not seem to strip the headers, so it must have been some intermediary system.Thanks for thinking with me
