You're correct: the COMPUSERVE.COM MTA is not following the RFCs. It should bounce it to the MAIL FROM:<ONWER-listname@listhost> address. I just got one of these babies today as a poster (not as a list-owner). This is an example of why list-owners should post an occasional message to their own lists i.e., as a bug-catcher. /Pete Weiss at Penn State |>From: Electronic Postmaster <[log in to unmask]> |>To: xxxxx <[log in to unmask]> |>Comments: Returned from: <[log in to unmask]> |>Subject: Undeliverable message |>Message-Type: Delivery Report |>Date: Thu, 14 Aug 97 17:53:04 +0000 |> |>Your message could not be delivered for the following reason: |> |>Mailbox 72153.2771 is currently full. |>Please resend your message at a later time.
