Mail servers are Windows 2000 with Exchange 2000 with all latest patches for both. DCs are Windows 2000 with all latest patches. Obviously no QB DLs since on E2K. Basically problem is that some people on the DL got a message the first time something was sent but when the very important followup was sent in a known time span (known that is to the users), they didn't get that. No change in status of the users who didn't receive the second message. No NDRs. No badmail. No log hits in the blocking software. No obvious errors anywhere. Tracking logs confirm the known users didn't get sent the message. Now trying to compare the several thousand users in the DL to who is in the tracking logs as having received the message to get an accurate picture of who all didn't receive the message. My main question is has anyone ever really took the time to verify that Exchange is actually sending messages to everyone on a large DL accurately and consistently? People tend to be pretty forgiving in terms of email delivery unless they expect something. Something going to a DL is not usually expected unless it is a followup to something else that someone is watching for. If someone doesn't get something that is a following, what is the method they will usually take to track it down? They won't, it is a pain in the butt to call the help desk, for something so simple they will ask their friend or ask the poster to resend that is if they even know something was sent at all. joe

Seems like you're on the right track. With the message ID and tracking logs, you can back out all of the mailboxes that got the message. But you already knew that, and probably have let loose a perl script on the logs. I suppose there may be a way to get a message into a mailbox without having events logged in the tracking logs, but I can't remember ever seeing that as long as logging was enabled. _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Wednesday, March 23, 2005 7:37 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] [OT] Another Odd OT Question - Exchange DL based but still has an AD portion...

I say it because some of the DLs I'm on, people would find out they didn't get the message. Such as a required form that they would not fill out. Did I call all 4000 people on one of these lists? No I didn't. Short of having a script that watches every mailbox, I suspect no one on this list can really answer that question. ~Eric -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Wednesday, March 23, 2005 4:48 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] [OT] Another Odd OT Question - Exchange DL based but still has an AD portion... How do you know it works just fine? What proactive checking is done to verify it? Say 2 people didn't get the message and they didn't realize there was a message to not get... The question is being posed because I am working with some folks who had a couple of people (that we know of) out of several thousand that got one message posted to a DL but didn't get an important followup message. It is slowly being reduced to either the expansion is screwed on the Exchange side or on the AD side and my bet is Exchange side as I don't expect AD would not return all users in a group without throwing at least one error. We know that it isn't a user issue because there is no evidence in the tracking logs of the message ever going to those people. Right now I am trying to get a comprehensive list of everyone who did get sent a message so it can be compared to the DL itself to see if it was just these two people or more. joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Eric Fleischman Sent: Wednesday, March 23, 2005 7:41 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] [OT] Another Odd OT Question - Exchange DL based but still has an AD portion... I'm on several DLs that are thousands of users in size(some are multiple times larger than MaxValRange), and it works just fine. (by thousands of users in size, I'm talking about a single DL that is thousands of users, not nested DLs, as that is of course an entirely different test scenario that may not hit ranged retrieval) Why do you ask? Is there a followup technical question? :) ~Eric -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Wednesday, March 23, 2005 3:04 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] [OT] Another Odd OT Question - Exchange DL based but still has an AD portion... Has anyone ever actually tested if Exchange properly delivers emails to all members of a large (many thousands of mail objects) Distribution List? Specifically where the Exchange server has to expand a DL and use attribute ranging to get all members. joe List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
