This seems to happen to a few domains, Bellsouth, hotmail, or my work domain, plus a few others I've tried to send mail to. It appears as though the DNR is originating from the external gateway because I'm seeing that it's receiving my email. _____ From: Periyasamy, Raj [mailto:Raj.Periyasamy@xxxxxxxxxxxx] Sent: Wednesday, December 24, 2003 9:54 AM To: [ExchangeList] Subject: [exchangelist] RE: Mail delayed and not reaching some external destinations http://www.MSExchange.org/ Marvin, Is this happening to only to a particular domain or to random domains ? Normally this happens when the destination domain's email server is unreachable, and the messages gets queued up in the gateway. This could be due to a problem with destination itself, or may be some Internet routing problem in reaching the particular domain, some where in the Internet. Usually this means the message will be retried again automatically. Is the NDR originating from your own gateway or some other external gateway ?

I get this error a couple of days or hours after sending the email. A search of this error on Google returns a few links that seem to point to the connection being refused but I'm not sure. Can anyone confirm and provide some type of direction on how to troubleshoot this? Any responses are appreciated. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------
