[Maybe this is some "quarnatine" processing?] Here's but one example. <Begin Forward> ------------------------------ Message in error ------------------------------- Received: from mail.northeastmedical.org (mail.northeastmedical.org [166.82.104.147]) by ES45.HSLC.ORG (PMDF V6.2 #30788) with SMTP id <[log in to unmask]> for owner-tvc-alert@LISTSERV (ORCPT [log in to unmask]); Fri, 22 Aug 2003 15:16:27 -0400 (EDT) Date: Fri, 22 Aug 2003 15:16:26 -0400 (EDT) Date-warning: Date header was inserted by ES45.HSLC.ORG From: [log in to unmask] Subject: Delivery failure notification To: [log in to unmask] Message-id: <[log in to unmask]> Your message with Subject: TVC Alert, 22 August 2003 could not be delivered to the following recipients: [log in to unmask] Please do not resend your original message.
