Exchange has a list of permissions that are assigned to each connector based on the checkbox selection below.
Here are an example of some SMTP headers that are used internally (in routing) to configure how exchange behaves:
ms-Exch-SMTP-Accept-Authoritative-Domain ms-Exch-Bypass-Anti-Spam ms-Exch-Bypass-Message-Size-Limit ms-Exch-SMTP-Accept-Exch50 ms-Exch-Accept-Headers-Routing ms-Exch-SMTP-Submit ms-Exch-SMTP-Accept-Any-Recipient ms-Exch-SMTP-Accept-Authentication-Flag ms-Exch-SMTP-Accept-Any-Sender
These headers are not visible in Outlook, but live in Exchange as a message is sent
What are the meanings/rights of these headers?
What headers aren't listed?
What permissions are assigned to each checkbox?
