It's the mail-list software - it adds a header line that contains the word "copy" in it. Gmail presumably looks for that line in incoming headers and /dev/nulls the message. Makes perfect sense and explains why I can't find any settings in prefs to offset the behavior. In the early days of gmail, I came across an explanation about this behavior in their docs, which stated that they would not list your own posts coming back to you from mail lists; this was touted as a 'feature' to cut down on volume in the mailbox or words to that effect - funny thing is, I've never been able to find their explanation of this behavior again, so I can't quote the exact words. I'd say, case closed. -- Claude Jones Bluemont, VA, USA
