Missing headers when using the Exchange 2003 Lotus Notes Connector (Redbull)
Some of you may have already noticed this, but I wanted to put this out there in an attempt to document just about anything I come across that is known to us here at Microsoft.
You may notice that if you bridgehead your mail on Notes and sit Exchange behind it that the message headers get stripped before it hits Exchange.
(Internet)-----(Domino/Notes)-----(Exchange)
This is known and by design. The "Received" headers are not copied to PR_TRANSPORT_HEADERS during conversion. This means that the only headers Exchange users will see are Exchange headers.
The only work around? Use SMTP for mailflow.
