    An MX record with 3 seperate IPs - how will it work

    we are looking at a setup of mx records similar to the ones below for our organization

    mx5 mail.smtpsvr.net
    mx10 mail.xyzsvr.com

    the twist is (mx 5) mail.smtpsvr.net has 3 IP addresses which route in through 3 different ISPs

    example
    mx5 mail.smtpsvr.net Addresses: 3 different Ips

    My question is this - if mail is sent to Mx 5 and one of the 3 IP addresses is down or unavailable - will mail attemp to route through the other 2 ip addresses for Mx 5 or will it bypass the other 2 IPs and go to the next record (Mx 10)?

    Also, are there any articles out there on such a setup? I haven't had any luck yet.

    Thanks,

    Mr Moto
