Currently we are having an idea of putting an exchange server for our emails at our domain hosted on a third party ISP which is situated in US whereas our office is located in Middle East.

We installed MS Exchange 5.5 on Windows NT 4.0 in our office.

How we can connect and take the mails from our domain and distribute the mails inside our office. (I want to make u one thing clear that we are not intend to access all the mail boxes of our domain but some mail boxes)

When I discuss this with some people here, they told me that we need a legal IP or We need a DNS server and some says that the ISP has to provide a MX record or something...

Is it possible to take the mails coming to our domain and route it to the exchange server inour office so that we can distribute the mail in our office?

Do You have any solution for this?

If you're going to route your Internet mail through your Exchange system, you have a couple options.

One would be to add a third-party utility that connects to your POP e-mail account and downloads the mail to Exchange (if you use the Small Business Server version of Exchange, it comes with a POP3 connector).

The second option would be to have your ISP act as a mail relay and send the mail to your Exchange server via SMTP. For this, you would need a real Internet IP and someone to host the DNS records for it - your ISP would be the logical company to do this if they are willing.

The third option would be to have your Internet e-mail come directly to your Exchange server and like the option above, you would need a real IP and someone to host the DNS records (the MX record is just a special DNS record that associates a mail server with a domain).

All are doable and not that difficult to set up. It sounds like option 1 might be the most reasonable for your situation.

Using the real Internet IP and MX record will force we receive all the mails coming to our domain. But i am not intend to do that. I am planning to route the mails coming to one particular set of accounts

Do you have an ISP locally? Do you have constant access to the internet? There are several ways you can do this. If you do not have access constantly, Exchange can configured to periodically dial out and collect email from a mail repository at anISP, using ETRN commands.

If you have access to the internet, just setup with your ISP an MX record that points mail destined for your domain name to come to your IP address of your Exchange server. You may check with Microsoft, because they hada POP3Gateway connector that only worked with Microsoft Small Business Server (SBS)'s exchange server (Exchange 5.5). This seems to be what you want. The connector would periodically (configurable) log in to pop3 accounts and direct the mail to the mailboxes that were configured to use the connector.

Let me know if this sounds like what you are wanting.

And I would like to clarify one more thing also that I need to have both incoming and outgoing mail facility. And I am not intend to go for the MX- Record idea. So is there any way we can set up this situation?

You might want to re-read the first option. It would NOT require a public IP and MX record and you could pull down mail only from selected accounts if you wished.

Another option would be to use mail forwarding on the existing mail server and just set up a forwarding address for those accounts you wish to forward. From re-reading the second-to-last paragraph in your question, it seems like that might be the option you're looking for. But it would still require a public IP to forward the mail via SMTP to your Exchange box.

Your answer is ok. But I didn't specify in my question that I am having a small business exchange server. And I know that I have to use some third party Pop downloaders. But My thing is I need clear cut reply which one and how I have to configure. Any way thanks for your help.

FYI,

We came across a software on Net which is called Mail essentials, a Pop3 downloader, and we achieved the downloading of mails from the pop account of ISP and forward that to Exchange server. Thanks for your replies.
