Forward email from host server to local exchange server

Ok. I just changed hosting for my dad's company to a new server.  Now his exchange server isn't getting email sent to them from outside the office. How do I forward all email from the hosting server to the local exchange server. Please help me. i have cpanel on my hosting computer but I can also get telnet access.

1/. What version of Exchange

2/. Do you just need to change MX records at InterNIC (ie you use DNS for mail delivery)  or do you actually download the mail from another server?

1. He's running Windows Server 2003
2. I thought I could just change the MX entry to the local IP but i guess that doesn't work.

When you say local IP did you change it to the external IP of the router? What is the current MX record IP?

Okay, so I'll assume that is Exchange 2003 as well.

ya I changed to the current external IP address. The ip of the exchange server is 12.146.30.90 The domain  is www.vaccaroseed.com and is hosted outside the office. I just updated the dns monday to point it to the new outside hosting server.

Thanks

Okay that sounds ok. You still have all the same port forwarding set up on your router?

Also when did you make this MX record change. MX records could take 24-72 hours to propergate and start working after a DNS change.

Ok,

so in Cpanel I can put in the IP address of the Exchange server for the New mx entry. It says I need a Fully Qualified Domain name. Is that all I need to do to start forwarding all email to the exchange server. Is there anything that i need to do on the exchange server end to direct it to the new hosting server even though the domain didn't change?

Thanks

No that should be all you have to do on the MX record. Just specify the external IP of your Exchnage server (or router) and if behind a route make sure all the right ports are forwarding to the Exchange server.

No changes on the Exchange server should be necessary if they are using DNS for delivery which it sounds like you are.

Gareth GudgerCommented:
Yes IP is fine. Never had a problem entering an IP myself. You are changing this in the MX record as well right?

our new host mail server changed from smtp.vaccaroseed.com to just vaccaroseed.com is this a problem?

Gareth GudgerCommented:
Argh...must have misunderstood you. So you download the mail from offsite? Are the clients using pop accounts or something?

If they are they you will need to change your mailservers in their email software to reflect the change.

OR

Is this a server hosted in your local network?

I think I just confused you a little bit. Vaccaroseed.com is hosted offsite. The exchange server is located at OUR office and handles the email. I want to forward all email that comes to vaccaroseed.com to the exchange server

Gareth GudgerCommented:
Oh ok....then all you need to worry about is the MX record pointing to that of you routers external IP and to be sure the router is forwarding port 25 to the IP of your Exchange server or DNS server (however you have it set up)
