Email Server and IP Address

By wesley ·
In our organization, we have an email server behind a router with NAT enabled. In about two weeks' time, we will have DSL installed, and a new IP address different from the current one in place. My question is, how and/or who should I contact to have email coming to our domain comes through the new IP address?
We currently have a third party hosting our web pages, only the email server is in house.
Thanks.

you have to get in touch with whoever hosts your Domain Zone files

tell them to change the IP address of the MX record to your new IP

Scary question, that is information that you should know at all times.
Open a command prompt, type "nslookup" then enter.
Type "set q=MX" then enter.
Type your domain name. example: "hotmail.com"
You'll get something like:
mail.hotmail.com internet address = 216.33.151.135

Who owns that server? You? Your ISP? Your co-worker? Find out and contact them, ask them to change the MX record for you.. or learn DNS and house your own DNS server.

Your provider of your DNS service will need to change the A record that your MX record refers to.
The instructions in Answer #2 will get you the proper information for your current mail server MX entries. However, this information is going to point to your own IP address for your mail server. You need to do a "set q=SOA", then enter your domain name. That'll give you the DNS server that hosts your domain. The owner of that is who you need to contact.
The real question is whether or not you'll be able to get a static IP address with your DSL service. Without a static IP address, you may not able to host your domain's email. It can be done, but it takes extra steps to update the DNS entries for your mail server host. Hope this helps!
