I will try this -----Original Message----- From: Almassud, Abdulmohsen (MJ) [mailto:aalmassud@xxxxxxxxxxxxxxxx] Sent: Thursday, December 01, 2005 2:42 PM To: [ExchangeList] Subject: [exchangelist] RE: please help exchange 2000 http://www.MSExchange.org/ I would check www.dnsstuff.com and make sure that your domain name is not black listed. They have a field where you put your external IP Address, and then they compare it to hundreds of black lists. Then I would make sure that there is a reverse DNS entry for the domain name being used. Hope that helps MJ Almassud Network Administrator MedQuest Associates, Inc. 4300 North Point Parkway Alpharetta, GA 30022 Email: aalmassud@xxxxxxxxxxxxxxxx Direct: 678-992-7266 Cell: 678-768-4854 Fax: 678-992-7433 -----Original Message----- From: clementa@xxxxxxxxxxxxxx [mailto:clementa@xxxxxxxxxxxxxx] Sent: Thursday, December 01, 2005 7:57 AM To: [ExchangeList] Subject: [exchangelist] please help exchange 2000 http://www.MSExchange.org/ Hi I use Exchange 2000 server and when users send messages to some particular domains, i get this error message: Attention: Non-Delivery Report This report is generated by the email server at: and attached to this report was not delivered to the following recipients: Address: sa@.....com Reason: 553 5.3.0 Rejected - see http://www.spamhaus.org (553) -------------- Please help Clem ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: aalmassud@xxxxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp ------------------------------------------------------ Visit TechGenix.com for more information about our other sites: http://www.techgenix.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: clementa@xxxxxxxxxxxxxx To unsubscribe visit http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Report abuse to info@xxxxxxxxxxxxxx
