I have a question with the following error, I believe it is because this user was subscribed from a 'fake' userid with an invalid account. This user has subscribed into the list numerous times, every time he subscribes there are handred of invalid (rejected) mails coming back to us the owners because his e-mail name does not exist. The following is the most recent subscription he did to the list, the list send a mail trying to Aknowledge the subscription and (of course) could not find the subscriber. I am trying to figure out a way that the list will flush this user from subscribing to it again, with this as a result it will never forward his mail to the members (since he will not be subscribed). Is there a way to do this, also how other people deal with situations like this ? I will appriciate any responces. /Spyros (sda106@psuvm) >*>Received: from BROWNVM.BROWN.EDU by PSUVM.PSU.EDU (Mailer R2.08) with BSMTP id >*> 1422; Sun, 22 Mar 92 15:52:23 EST >*>Received: by BROWNVM (Mailer R2.08 Be) id 1081; Sun, 22 Mar 92 15:51:42 EST >*>Date: Sun, 22 Mar 1992 15:51:42 -0500 >*>From: Revised List Processor (1.7b) <[log in to unmask]> >*>Subject: Delivery error notice sent to LISTSERV >*>To: "<Spyros D.
