    Default Internal Mail Delivery Fail dnsmasq

    I've been trying to setup a split zone DNS because our mail server is behind a firewall. I know this issue has been brought up a million times but I can't seem to get it working. When I change the listening port of the DNS server to (10.1.10.199) and change our clients DNS to point to (10.1.10.199), we no longer receive emails through IMAP. When you run a digg command, it shows that mail.mydomain.com resolves to (10.1.10.199). You also can't access the web interface by typing https://mail.mydomain.com you have to use (10.1.10.199). Any guidance would be greatly appreciated, here is our setup.

    Server OS = Ubuntu 12.04
    Zimbra Version = 8.0.7
    DNS Server = dnsmasq

    resolv.conf
    Code:
    nameserver 127.0.0.1
    /etc/hosts
    Code:
    127.0.0.1         localhost.localdomain localhost
    10.1.10.199       mail.mydomain.com mail
    /etc/dnsmasq.conf
    Code:
    server=208.67.222.222
    server=208.67.220.220
    domain=mydomain.com
    mx-host=mydomain.com,mail.mydomain.com,5
    listen-address=127.0.0.1
