Greetings Rishu, All you need to do is add an additional SMTP domain and it will allow the exchange 2003 server to receive email for both domains. You will have to also modify your MX records in DNS to point to the new SMTP gateway server ( Microsoft Calls it a Bridgehead in 5.5 and Front End Server in 2000/2003 ). http://support.microsoft.com/kb/321721 A good book for EXchange 2003 that explains these concepts is: Microsoft Exchange Server 2003 Unleashed by Rand Morimoto http://www.bookpool.com/sm/0672328070 Jose ----------------------------------------------------------------------------------------- ----- Original Message ----- From: IT Buzz To: exchangelist@xxxxxxxxxxxxx Sent: Monday, March 26, 2007 10:33 AM Subject: [ExchangeList] Urgent help needed Dear All, We are going to change the website name from xyz.com to abc.xyz Want to receive mails from both the domains ( xyz.com & abc.xyz) parallely Right now we don't want to change any thing in current setup (rename Domain name, etc), but want to configure exchange to recieve & distribute mails for both mail ids.
