rrdavis07 Posted June 12, 2007 Share Posted June 12, 2007 I'm the new email administrator at my new job, trying to figure out a delivery issue we are having through our Exchange 2003 server. In the process of investigating the problem, I ran across a reference to SpamCop in a problem report peripherally related the the issue I'm investigating. I would appreciate any assistance I can get to rule out (or in) SpamCop as part of our problem. We have an Exchange 2003 server running over Win2003 server. When I send an email out to a distribution group that is comprised of external email addresses, I get Non-delivery Reports back on probably 20% of the list. Then, on June 4 I happened to set up my Outlook here at the office to access my home pop3 account and have been receiving my home email here at the office since that time. This was not related to my investigation, but on June 9, I received the following email -----Original Message----- From: Texas Christian University LISTSERV Server (14.4) [mailto:LISTSERV[at]LISTSERV.TCU.EDU] Sent: Saturday, June 09, 2007 12:00 AM To: Randy Davis Subject: Your removal from the SCOUTS-L list Sat, 9 Jun 2007 00:00:27 You have been automatically removed from the SCOUTS-L list (SCOUTS-L - Youth Groups Discussion List) as a result of repeated delivery error reports from your mail system. This decision was based on the automatic error monitoring policy in effect for the list, and has not been reviewed or otherwise confirmed by a human being. If you receive this message, it means that something is wrong: while you are obviously able to receive mail, your mail system has been regularly reporting that your account did not exist, or that you were otherwise permanently unable to receive mail. Here is some information which may assist you or your local help desk in determining the cause of the problem: - The failing address is randy[at]DAVISFAMILYONLINE.NET. - The first error was reported on 2007-06-04. - Since then, a total of 93 delivery errors have been received. - The last reported error was: 5.0.0 550 188.8.131.52 is listed at bl.spamcop.net PLEASE DO NOT IGNORE THIS MESSAGE. While you can of course re-subscribe to the list, it is important for you to report this problem to your mail administrator so that it can be solved. This problem is not specific to the SCOUTS-L list, and also affects your private mail. This means that YOU HAVE PROBABLY LOST SOME PRIVATE MAIL AS WELL. Anyone trying to write to you during the same time frame will probably have received the same errors for the same reason. The SCOUTS-L list is but one of the many people who may have tried to write to you while your mail system was malfunctioning. DO NOT LET TECHNICAL PEOPLE CONVINCE YOU THAT THIS IS NORMAL. It is never normal for a mail system to claim that a valid, working account does not exist, just as it would not be normal for the post office to return some of your mail with "addressee unknown" when the address was written correctly. It is true that some mail systems are less reliable than others, and your technical people may be doing the best they can with the tools they have. But, ultimately, the level of service that you are receiving is the result of a business decision, and not something due to a universal technical limitation that one can only accept. Reliable mail systems do exist, and it is ultimately up to you to decide whether this level of service is acceptable or not. Note the bl.spamcop.net reference in the email. This is my only clue that SpamCop might be involved in this issue. While this appears to be peripheral to our Delivery Failure Reports, it is too much of a coincidence to ignore. Outgoing corporate mail is receiving Delivery Failures on certain addresses--most of which are known to be valid, then when I start accessing personal mail, I begin to generate deliver errors on what is obviously a valid address. I don't know enough about SpamCop to know whether it is part of the problem or not--Please help me rule them in or rule them out. And answer why they were listed in my delivery failure report. What additional information will be useful to make this determination. To my knowledge, we do not use the services of SpamCop. We are an educational institution and only send external emails to parents and other stakeholders of the school, along with other contacts necessary to conduct our business.

Information about SCOUTS-L and my personal mail: I continued receiving messages from the SCOUTS-L List, but apparently, 93 other messages were bounced back. The first bounce occurred the same day I started accessing my personal email through our corporate email server. No problems before this. I continue to receive other email, however I have never received a particular personal email from a sender who assures my he sent a message twice, but I never received it and he never received a delivery failure report. Information regarding mail sent from our email server: A test email I sent out produced 135 Delivery Failure Reports. 3 of these reports came in messages generated by the recipients mail server (YAHOO). The rest were messages generated by our own server. Error codes included: 5.5.0; 5.1.1; 5.3.0; 2.0.0; and 5.7.1. I realize that some of these errors will be legitimate (address typed in wrong, etc).
