Hi, Presently in my office, Exchange fetches the mail form a third party mail hosted server and distributes among users. I want to change the configuration of exchange to send / receive mails directly to / from our exchange server hosted in our office. We have the following: 1- Exchange 2007 installed server 2- Domain name, say mail.xyz.com 3- One public static IP address and internet leased line 1 Mbps. 4- Windows 2008 Domain Controller Please describe the setup of the same step-by-step since I am quite new to Exchange 2007. Your help is highly appreciated, Best regards, Shafeek

Hi, Its suggest to have a anti-spam gateway if you point it directly to exchange then you won't have any gateway to scan mail & if that not required then you gave to changed the MX record which right now will to pointing to that 3rd party mail hosted server, point that MX to you exchange public IP & for out going there will a send connector pointing to 3rd party host server remove that or point that to internet, have a look into this article for that : http://www.petri.co.il/configuring-exchange-2007-send-external-email.htm. Do let us know in case more info is required.Ripu Daman Mina | MCSE 2003 & MCSA Messaging | MCC

Hi, You also need to modify the send connector configuration. Now the send connector is setting as “Route mail through the following smart hosts”. You need to ticket this option “Use domain name system (DNS) ”MX” record to route mail automatically” For the security reason, I suggest you use ISA 2006 to publish Exchange server. ISA 2006 and Microsoft Exchange Server 2007 are designed to work closely together. Publishing Exchange Server 2007 with ISA Server 2006 Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
