RFC 1123 (aka STD 3), Host Requirements, section 5.3.3. In part: If there is a delivery failure after acceptance of a message, the receiver-SMTP MUST formulate and mail a notification message. This notification MUST be sent using a null ("<>") reverse path in the envelope; see Section 3.6 of RFC-821. The recipient of this notification SHOULD be the address from the envelope return path (or the Return-Path: line). So it's not actually required, just encouraged. Software written nearly ten years after the standard was published should be able to do this, though, and it's what mailing list software expects. It's also not using a null envelope sender in its message, which it MUST do. Elsewhere in this RFC is the requirement for a "postmaster" mailbox. I suppose I should wish them luck... -- Carey Evans http://home.clear.net.nz/pages/c.evans/ Larry froze. Was the bag a trap? He could see the way in, but the other end appeared to be sealed.
