That seems to work, except that you lose information (the sender's address) I would find that quite unacceptable. We need to know who said what in an IETF discussion, and having to poke around in the headers to find the original sender would be very painful. It would make some archive searches impossible, too. Data: I just had a quick look at my mail archives going back N years. I find 119 messages with 'yahoo' in the From field out of 52367 with 'ietf' in To or CC. Brian
