Thanks. We'll let you know when a new response is added.

First things first see if your internet provider blocks port 25 also ask them if running a mail server would violate their terms of service. I wouldnt want to lead you down the wrong road! Also if you can ask them for an upgrade in service they can and will provide a static IP address for a small monthly fee. Then you can set the box up normally.

If you dont want to spend the money or your company told you no then you can look into a web service called dynDns located at www.dyndns.org .

Basically it has a client that goes on your box and when it changes IP addresses ( mine has not changed in the last 3 years on Cablevision) it updates it on the web. So you will have a servername like Yourname.DynDns.Org that will always pojnt to your box regardless of what internet IP it has.

I know dyndns.orf i have created my domain account on it tell me one thing what to write in MX Hostname will it be like mycompany.com or the domain name i have created on dyndns

First of all if your on the internet you hava a public IP address, just not static!
Second, I guarantee you’ll have problems sending e-mail thru exchange on a dynamic IP address, many ISP’s are now blocking dynamic IP ranges that use a mail server.
Third, as far as receiving e-mail, you must have a registered domain name from a registrar like doster, godaddy, etc., then use dyndns or zoneedit(both free) to point your domain name to your dynamic IP. I use directupdate to monitor my IP and change it on zoneedit as needed.

    You have to have MX record that will point to your exchange server. Setting up an Exchange server is more complicated then installing the software. Review how to setup A record and MX record. You will have to find someone to host your DNS records.

    no port 25 is not blocked my company is already using my ISP email, well yes this is the case they don't to invest money on Public or a static IP, i can send the email but cannot receive it. I have told my domain host to create A record and MX record i think that should solve the problem, however my domain host has given me his IP i need to know that do i have to put this ip in my dns or in exchange anywhere.
