bounce emails

I'm going to assume this is an Exchange environment?

In Exchange 2003, you may have recipient filtering turned on. This will bounce incoming emails if the address does not match a user's email address in the GAL.

In Exchange 2010, recipient filtering is handled by the Edge Transport server.

here's a decent, easy read... http://www.msexchange.org/tutorials/Sender-Recipient-Filtering.html

...and for Exchange 2010: http://technet.microsoft.com/en-us/library/bb123891.aspx

Yes, sorry! this is an Exchange 2003 environment, but here is more information i got when they send a message this is what they received:

"They" who? the sender receives this, or the recipient?

The sender...

Do the recipients get anything? I don't see anything in those headers that looks like a bounce message. Do the exchange server logs report anything at that same time?

Also... There are 2 different email address domains that the email is being sent to. Are both having the issue?

Yes, the recepients get some items too.

How do i check the exchange server logs for any issues?

Yes, both having this issue.

ok.. I think what is happening is that somewhere the formatting (don't know the exact term) of the email is being lost.

if you save that email posted above on your desktop as a .eml file, can you open it? I just did and was able to open it in outlook. It has 1 Word document attached called "Sparkroom R&D Status Report - 11.05-2010.docx." I cannot open the attachment since I don't really have the email.

What client are you using to send and receive these emails?

Here's what it looks like on my system....

I understand what you mean...sparkroom users are using some sort of web-email like google or something like that, and the receiver end is using outlook 2007.

I'm going to guess that when the user opens the email on, say Outlook, this is what they see? If that's the case, it looks like something (possibly the originating client or server) is adding an extra line-break in the headers. What *does* View -> Options show as the header?  The first blank line, by Internet standards, marks the end of the header fields. Everything after that is assumed to be the body of the email.
Other's have had this error... now we just need to figure out how to fix it.
