Dear sirs, I have got a problem in sending a mail to list in our side. We created a test list under LISTSERV in our node. When someone in the list sent a mail to the list. Several UNNAMED MAILs were sent to the postmaster by error. Obviously, the mail was not distributed to the list members. Is anything wrong here? The rejected mail was as following: Received: by TWNMOE10 (Mailer R2.02A) id 0913; Thu, 30 Mar 89 16:07:16 CST Date: Thu, 30 Mar 89 16:07:12 CST From: Network Mailer <MAILER@TWNMOE10> Subject: Undelivered mail To: LISTSERV@TWNMOE10 Your mail was not delivered to some or all of its intended recipients for the following reason(s): FROM: or SENDER: inconsistent with spool file origin. --------------------RETURNED MAIL FILE-------------------- Received: by TWNMOE10 (Mailer R2.02A) id 0910; Thu, 30 Mar 89 16:07:12 CST Date: Thu, 30 Mar 89 16:06:33 CST Reply-To: LISTSERV TEST LIST <TEST@TWNMOE10>, JHCHEN@TWNMOE10 Sender: LISTSERV TEST LIST <TEST@TWNMOE10> From: JHCHEN@TWNMOE10 Comments: To: TEST@TWNMOE10 To: MOE01@TWNMOE10 TEST................
