To transmit a message, transport providers

When a message is sent to a variety of recipients with several messaging systems, each transmitted copy will have a different sender identity.

The transport provider or tightly coupled message store and transport is also responsible for setting originator and reply-to information. Originator information is stored in the PR_ORIGINATOR properties and reply-to information is stored in the PR_REPLY properties. The client can set these properties; however, the transport provider is allowed to ignore and overwrite the client's settings.
