Only the copy that went through the mailing list has those, because they are added by the list management software and not by sender's email client. So the copy that was sent off-list directly to you doesn't have any of them (unless you add them yourself on your side uning eg. some filtering rule). So, if the list copy comes first, the direct copy is deleted and everything is ok. But if the direct copy comes first (and thus list copy is deleted), it doesn't have those headers. So if you reply to it, the copy goes only to Bob and not to list. -- 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."
