I'm in the process of migrating our environment from Exchange 2003 to 2010. For a while now, I have been receiving messages from postmaster@domain.com, most of which look like this:

To: Me

From: postmaster@domain.com

Subject: Blablabla


Delivery has failed to these recipients or groups:


The e-mail address you entered couldn't be found. Please check the recipient's e-mail address and try to resend the message. If the problem continues, please contact your helpdesk.

Diagnostic information for administrators:

Generating server: exchange2003server.domain.com


< #5.1.1> #SMTP

Original message headers:

Received: from iis_server ([IP address]) by exchange2003server.domain.com with Microsoft SMTPSVC(6.0.3790.4675); Fri, 30 Nov 2012 06:11:54 -0800 MIME-Version: 1.0 From: Someone To: Date: Fri, 30 Nov 2012 06:11:54 -0800 Subject: Blablabla Content-Type: text/html; charset="utf-8" Content-Transfer-Encoding: base64 Return-Path: Someone Message-ID: X-OriginalArrivalTime: 30 Nov 2012 14:11:54.0667 (UTC) FILETIME=[A6AB37B0:01CDCF04]

I received another message today that I believe was supposed to be quarantined (subject line was just [QUAR]) that was for another user entirely.

Why am I getting these?


Your email address is designated as the email address to send a copy og NDR's to on the Messages tab of the Default SMTP Virtual Server on your Exchange 2003 server.

  • Herp, thanks very much. No idea why that would have been configured like that. I've removed my email address and presume I won't see these anymore. Thanks! – NaOH Nov 30 '12 at 19:24
