I just finished configuring my first Exchange Server 2003. Now I would like to send/recieve e-mail on the internet, but I don't know who I need to call or what to do.

We have an internet domain name called somedomain.biz. that we don't use and ourcompany.com that we use. We have 20 unused static IP addresses from our ISP. Let us say I want to use 172.186.1.x for the Exchange e-mail server.

Question:
1) Do I only call the ISP to tell them to create an mx record for the e-mail server (webmail.somedomain.biz)?

2) Do I need to call the company that we bought the domain name and ask them to assign the e-mail server's external IP address to the domain name?

our e-mail to ourcompany.com is currently hosted by a 3rd party e-mail provider. Since we want to host our own e-mail,

3) Do I need to call the company who is currently hosting our e-mail addresses for @ourcompany.com as well?

Is there any changes I've to make to the Exchange server? For example ... the Exchange Recipient Policy

This is my first assignment, pease give me some sort of hint.

Alen Bemider,
First assignment is always difficult, but you will get it right, I am sure.

Yes you will need to call your ISP and have them add the MX record into their DNS servers.

==================================================
MX record has to point your Mail Exchange server.
This will be done on you ISP, just call them.

Open SMTP (port 25) and point it to your Exchange server
this will be done on your network, on the firewall or router.

As you said if we assume the IP address is 172.186.1.x=========> this is the IP address of you Exchange server,

I do not know your environment, if you are behind the firewall; you will have to open SMTP port 25, and point it to your Exchange server as well as the Public IP address, if you are using private IP address internally for your mail server.

An MX record normally takes 48Hours to replicate, and you will have to wait, in order to receive and send e-mail, anyway.

Second question,
Answer is NO, you don�t have to call anyone except your ISP, and have them Ad MX record, and Reverse DNS record for your mail server, onto their DNS servers.
You will need to have a Public IP assigned to your Exchange server anyway.

Last question is,

Yes you will have to call the company who ever is hosting your e-mail currently and tell them, you are going to host the e-mails. They will know what to do, and ask them what is the best way to get all current e-mail data to your mail serverm since you will host it inhouse.

Thank you for the response, OZ.

Here is my network setup, if you may have additional suggestions or advices:

ISP
|
|
|
(172.39.**.27) (172.39.**.20)
Exchange 2003 _ _ _ Cisco Router (NAT)
(192.168.1.10) (192.168.1.1)
|
|
|
Internal Network

I will call the ISP the first thing tommorow! Unfortunately, I forgot my long distance code [Smile]

Here is what you need to do about the ip addressing for your Exchange 2003 server.

This Exchange 2003 server will have two ip address. One ip address is the public ip address, which will be one of your 20 static ip address which your ISP is providing to you. The other ip address is private ip address which you are going to assign to your Exchange 2003 server. This ip address is going to be your internal network address. Make sure that this address is a static ip address and that your Excahnge 2003 server is not acquiring an ip address from a DHCP server(Remeber Windows operating systems are configured by default to dynamically assign ip address, i.e. to acquire an ip address from a DHCP server. Also most off the shelf routers i.e. Linksys, Netgear, D-Link, are configured with their own DHCP servers which is by deafult enabled.) The interal ip address should always be static internal ip address. Now in your router/firewall that you have you are going to create a NAT rule which will translate your the public static ip address (which you choose to assign) to the private staic ip address (you also choose to assign to your excahnge server).

Let us review what you are need to assign the Excahnge server two static ip address one public and another private. And you are going to use NAT
to translate public ip address to private ip address.
