relaying denied between 2 exchange 2003 servers in the same domain
I have an exchange 2003 server running on win svr 2003 that is connected to the internet and handles all email for our domain. I have built a 2nd exchange 2003 server running on win svr2003 that runs in the same domain. I aim to move the email boxes from the original physical server to the new virtual server and then decommission the old server.When I move user mailboxes from the original email svr to the new svr, users can send and receive emails internally, they can receive external emails from the internet but they cannot send emails external to the internet.The error msg is smtp 550 relaying denied.Any help would be appreciated. Thanks

Hi,Did you updated DNS configuration properly? You need to update MX and A, PTR record also for reverse DNS. Make sure that you don't have double entry for anyone which points to old server.Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

AmitThanks for your reply.I want to move the users over from the old server to the new server in a phased process so both servers will need to be running during the migration. Once all the users have been moved over i will then decommission the old server and ensure dns, mx records etc point to the new server

Hi, Does the issue happen on all users or only users whose mailbox is in the new server? Regarding the migrate steps, please refer to the following KB article: http://support.microsoft.com/kb/822931/en-us Please download ExBPA to have a health check for the Exchange Server. If the issue persists, please zip the report and send to me, I will help you check it. Thanks,Elvis The Microsoft Exchange Team Blog - You had me at EHLO - http://msexchangeteam.com/
