Hosting email server with MS Exchange on NT:

This instruction is applicable to MX Exchange 5.5.

Procedure:

·         Ask your ISP(eg. @work or uunet)  and Domain Name register(eg. NIC or registor.com)  to add an A record to their DNS Zone file.  They need to link your IP address(eg. 216.216.189.195)  to your domain name (eg. www.digital-us.com).   It is necessary to request for a MX record to point to your Email server.  You also need the DNS server's IP address from your ISP.  Need both the primary(eg. @work 24.2.68.33) and the 2ndary IP addresses.  These IP addresses will be used later. The information need to be added to your Zone file on ISP and Domain Name register's DNS are as follow:

·         This file can be found at winnt/system32/DNS folder.  It is created by DNS manager. Go to Network properties, Protocols, TCP/IP:  Enter IP address and subnet (255.255.255.0).  Gateway IP is the SDSL modem(216.216.189.193) or ISDN router's IP address.  DNS is the IP's obtained from ISP.  If your server also run DNS, then use that server's IP address as well.  Maximum is three DNS IP's.  WINS server is the internal computer names(such as DCS01, 200mmx) resolving server.  Ours is 216.216.189.195 (DCS01).

·         Check for valid IP's: from Command Prompt, type nslookup <ent>, set type=all <ent>, digital-us.com to see the IP mappings. Type exit to exit nslookup.  Or simply type nslookup mail.digital-us.com to see the the result.

·         You may test the Internet connections by type ping IP(eg 24.2.68.33) to ping the other server.

·         Install MS Exchange Administrator from CD.  Create a new site, digital on Server DCS01.

·         Open MS Exchange Administrator, Configuration/Connection, Create/new others, choose Internet Mail Service.   All settings should use default settings.

·         Create Recipient accounts using NT’s Username and password

·         Reboot NT
