I'm the email administrator at my new job, trying to figure out a delivery issue we are having through our Exchange 2003 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 25% of the list. Of the 135 NDRs received, 3 were directly from the Yahoo Mailer-Daemon, 22 were from the "System Administrator" returning various codes of 5.5.0; 5.1.1; 5.7.1; 5.3.0 and 2.0.0 and the rest were listed in a single long email from "Administrator", stating that the delivery to the following recipients failed. No error code or anything else was given.
Incidently, on June 4 I 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 re a listserv to which I am(was) subscribed through my home account:
While this appears to be peripheral to my 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 delivery errors on what is obviously a valid address.
If anyone has any thoughts on this, I would be grateful.

I realize that this may be two unrelated issues, but I doubt it.
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.
