    I woudl like to fix this problem

    Can i get a second server running cpanel and config it to be the backup mx server and backup dns server?

    If so is there a script i can get it to do so?

    Hi,

    For DNS you can use http://www.cpanel.net/products/dnsonly/

    This is free and very easy to configure.

    For mail this is not so easy, if your sever is down, no email will be deliverd or sendt with it so it only lays in the outbox or in a other queue. Hopefully it will not take you many days to fix the server :) If you just want a secondary mx to store the mail to your mailserver is up again, you can use EasyDNS or perhaps take a look if someone offers this for free.

    On the secondary server, add the domains that you want to receive/collect mail for to /etc/secondarymx.

    Ensure that the secondary sever is the next highest priority in DNS for the domain and if the primary server goes down, the secondary will accept mail and will attempt to deliver it to the primary until it's back up.

    Regards,
