My earthlink co-owner has had similar problems emailing a list on a different host, but same DNS lookup timeout problem. I suspect a problem with earthlink's network. /P Status: U Return-Path: <> Received: from smtpauth08.mail.atl.earthlink.net ([209.86.89.68]) by mx-austrian.atl.sa.earthlink.net (EarthLink SMTP Server) with ESMTP id 1dK1mx1fn3Nl34j0 for <[log in to unmask]>; Sun, 19 Jun 2005 11:05:29 -0400 (EDT) Received: from exim by smtpauth08.mail.atl.earthlink.net with local (Exim 4.34) id 1Dk1MW-0001le-LI for [log in to unmask]; Sun, 19 Jun 2005 11:05:28 -0400 Auto-Submitted: auto-generated From: Mail Delivery System <[log in to unmask]> To: [log in to unmask] Subject: Warning: message 1DjI8H-0002lw-AA delayed 48 hours Message-Id: <[log in to unmask]> Date: Sun, 19 Jun 2005 11:05:28 -0400 X-ELNK-AV: 0 X-PMFLAGS: 33554560 0 1 PJA4Z8WR.CNM This message was created automatically by mail delivery software.
