Switching from Linux to Windows Server

    I'm in the process of switching a company server from Linux to Windows. As it stands, I've set all domains and email accounts up but need to know what will happen when I change the DNS of the domain.

    www.domain.com
    -> Is a windows user using WLM as the mail client
    -> Is a mac user

    When I change the name servers for domain.com, what happens to the client email accounts? Will it be a case of not needing to change anything or will all emails be wiped from their machines?

    The DNS settings for domain.com are mail.domain.com but I need to know (especially with the mac users) whether or not the DNS will resolve its self rather than having to delete the account from the client machine and set the new account up (which will wipe the emails).

    Thanks

    Scott,

    This depends whether they are using IMAP or POP3. Your client should still receive new mail, and keep a cache of old mail already received if you're using IMAP. You will want an MTA running on port 25/465. You will also need to setup credentials for each mailbox. If you weren't moving to Windows, I would have advised you to run Postfix with mysql backend and Postfixadmin to make it tons easier to setup email routing, transports, forwarding, and group aliases. To answer your question, nothing happens to the accounts, they just remain on the Linux server. If you setup DNS like so, it will make things a lot easier:

    The above is BIND syntax, so adjust as needed, the point being you want the lowest TTL value that BIND supports, which is 5m (300s)
