    Hi,

    what are the steps we will need to do to ensure our emails still get to us,
    when we have a new IP address. (change office location and change of ISP)

    thanks

  2. In
    Internally, none of your IP addresses ought to change, as I imagine you're
    using NAT somewhere and private addresses on your LAN. Re-run the CEICW and
    it should take care of what you need (aside from anything you need to do in
    your router/firewall).

    You'll likely need to change your domain's public DNS records as well, if
    you host your own mail, etc.

    Go to the site where you domain name is registered and change your "A"
    record for the mail server to your new IP address.

    hi,

    when i rerun CEICW,
    it does not ask my new IP address, but just my new DNS details (from new
    ISP)

    is it sufficient?

    Also, i have requested my host for our domain to point A records to the new
    IP address.

    Are there anything i need to do to ensure that the IP address will resolve
    with the DNS etc?

    thanks

    Alan,

    To get your mail, you'll need to verify that your MX (Mail Exchanger)
    records are pointing to your new Ip address.
    This is a really cool site to verify your information and will test your
    DNS, WWW, and MX records.

    http://www.checkdns.net/

    After getting to the site type in your domainname and select check.
    If any section fails you'll need to contact the company that's hosting your
    domainname or Dns records.

    Thanks for using SBS2003
