If you are using Windows server 2008 SBS or Exchange 2007 or Exchange 2010 you send with your e-mail also mail headers that (I think) you would not like to “share” with external world:

If you want to remove this stuff we need to create a Hub Transport Rule:
Open Microsoft Exchange Console
Navigate to:
Microsoft Exchange \ Organization Configuration \ Hub Transport \ Transport Rules
Right Click and select New Transport Rule and name it “Remove headers” click Next,
chose From users inside or outside the organization and select Inside click Next,chose Remove header and as message header just write: Received twice click Next…
You are done… Headers will not be sent any more to users outside the organization…
Bye,
Luka (under influence of wonderful NT Konferenca 2010)
