As a close colleague of mine once said for a LARGE piece of corporate software we built and maintained: "It is not known not to fail." I think we'll have to set this aside and see if it never happens again. My last "Fail" notification was received yesterday: From: trinity-users-help(a)lists.pearsoncomputing.net To: trinity(a)jonz.net Date: 4 Oct 2012 08:52:06 -0000 Subject: warning from trinity-users(a)lists.pearsoncomputing.net but the report was for a list message dated Sept 22: Reporting-MTA: dns; vali.starlink.edu X-Postfix-Queue-ID: AA46E456024C X-Postfix-Sender: rfc822; trinity-users-return-3615-trinity=jonz.net(a)lists.pearsoncomputing.net Arrival-Date: Sat, 22 Sep 2012 10:43:34 -0500 (CDT) Final-Recipient: rfc822; trinity(a)jonz.net Original-Recipient: rfc822;trinity(a)jonz.net Action: failed Status: 5.7.1 Remote-MTA: dns; mx1.operationenterprise.com Diagnostic-Code: smtp; 550 5.7.1 sender domain does not exist Why the bounce was 'held' for 12 days before I was "warned" is strange. I don't think the MTA for pearsoncomputing.net re-tried the message every day for 12 days and then reported - by date- the first failure. I'll reply to this list message if I see another "warning".
