    Hello,

    I am trying to move a site from one server (cPanel) to my server (cPanel). The problem is that the user does not want email interrupted, during the DNS update.

    Is there a way to forward all mail from the old server to the new server via IP address? Can this be done by changing the MX record or something?

    Thanks

    Go on, have a guess
    There's nothing you can do to avoid email ending up at either server udring propogation (which you should expect to take at least 72 hours). The simplest way would be to have the user login to the old servers IP address and the new one via POP3 for the duration of the DNS propogation.

    you could also lower the TTL for the MX record (and all DNS records for that matter) and wait about 24-48 hours. after that time, have the domain setup on your box and then point the DNS to the new IP.
    Might be a bit trickier if they are redelegating to your DNS servers also, in which case, as chirpy said above, there will be delays, and there is nothing you can do about that.

    Another alternative, and this is a bit of work, would be to mount the directories from the old machine onto yours for the time being so that they check your machine and they will receive the mail via an NFS mount?? This would require the co-operation of the other parties however... If you own bot machines, no problem though..

    I agree, these are the facts of the matter. We have addressed this issue before in a few ways:
    * Used fetchmail to transfer email from the old server to the new. You unfortunately need the login and password for each mailbox concerned to do this. Other than that, it works just great.
    * Temporarily pointed a subdomain, e.g. oldmail.server.com, to the old server and let clients access email from there via POP or IMAP.
