Indeed. [EMAIL PROTECTED] can automatically unsubscribe me should my email address become unreachable. Someone posting to this list cannot, and thus has no use for bounces, out of office messages, delivery notifications and what more. Subscribers to a list shouldn't need to know who else is on the list. I post to the list, and as long as this part is transmitted OK I'm fine. Whatever happens thereafter is the list's problem. I even can agree with adding a "Sender:" header, to overcome MSes problem with their SenderID use of SPF records. Alex
