It does not. The feature you are requesting would cause it to do so. > As noted often envelope sender goes into return-path header so whats This is the FINAL envelope sender that your receiving MTA sees. What you are requesting is that SENDING MTA (and possibly any other on the way relaying the mail) puts the INITIAL (or intermediate) envelope sender it receives into "Received" header. This can be different from the final one and that information can indeed be private. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
