    Default [SOLVED] new 5.0.8 server having problems DNA/MTA

    Im having issues trying to figure out how to get split domains to work propertly, i dont remember having to do this on my previous installations.

    currently running 5.0.8

    my problem is that when enable DNS lookups are on im able to send email externally. but not internal emails nor can i recive external emails.

    When i turn that off
    internal emails work, and i can recive external emails, but all sending to external emails bounce.

    ive looked at my host file

    it contains:

    127.0.0.1 localhost
    (192.168.1.10) mail.domain.com mail

    listed in it.

    and my internal dns server is (192.168.1.5) locally

    my extneral ip is (70.1.1.1)

    in my previous configurations enable dns lookups was always on.

    i just cant figure out how to make mail.domain.com point to (192.168.1.10) instead of (70.1.1.1) when enable dns lookup is on.

    ive checked the wikipedia page, but im having trouble figuring out exactly what i need to do to get a split dns working.

    am i correct in assuming i just need something in my host file to fix this?

    you need to be running an internal dns server either on another box on your insiden etwork, or on the zimbra host itself. Then you define mail.domain.com to be the 192 address instead of outside. You point your zimbra server to this dns server so that it resolves your mail.domain.com to an inside address but all other dns requests go to the internet

    Ive tried this a couple of times now to no avail, both times i tryed to use bind9 to set up a dns server locally have it run automatically, something bad has happened and postfix stopped working.

    im just looking to figure out why from 4.5.6 to 5.0.8 with no firewall changes, and as best i can remmeber no diffrent in configruation, why im having problems with the "enable dns lookup"

    Post the output of the following commands (run on your zimbra server):

    Code:
    cat /etc/hosts
    cat /etc/resolv.conf
    host `hostname`  <--type that command as you see it here with single quotes not backyicks
    dig yourdomain.com any
    dig yourdomain.com mx
