    Default Network problems

    Looked at many topics about this. Tried a few.

    Now in a situation where only ldap starts (guess I should have taken a backup like recommended. Slap me).

    Everything was working like it should until this attempt to fix/change hostnames.

    History: I have an internal LAN (192.168.x.x), I have an external WAN connection. Installation occurred on the internal LAN (all references to the
    192.168.x.x address).

    Why I wanted to change things: Couldn't see certain admin pages when doing internet requests (pages were being referenced to my internal LAN address).

    Reconfiguration attempts: 1) tried the postconf example. No success system still okay 2) tried the libexec/zmsetup.pl example. No success, system screwed 3) Tried the zmsetservername example. No success, system still screwed

    This was an install from the rpm supplied on your site for FC4. There have
    never been any mods to the config before this stupid attempt to fix things.

    I managed to get the system back up and running but now it won't receive mail.

    I have tmocon.com defined as a domain in zimbra.
    I have an internal (office.tmocon.com) and
    external dns (tmocon.com)

    dig returns this:

    [root@enterprise zimbra]# dig tmocon.com MX

    vortex.tmocon.com and enterprise.office.tmocon.com are different interfaces on my zimbra box. vortex has a public static IP address, enterprise has a private static IP address (192.168.2.2)

    Similarly tmocon.com is also known as valiant.tmocon.com. This is the box that runs my dns. tmocon.com has two interfaces, one has a public static IP Address and defiant has a private static IP Address (192.168.2.1)

    Currently, there is no firewall.

    When I send a test message from tobuck@cawsey.com to to1@tmocon.com
    this is what is dumped in the log

    The temporarily suspended message is interesting. Is postfix trying to talk to port 25 on tmocon.com? If that is the case, why? The MX record for tmocon.com shows that vortex handles the mail...

    Also, I was trying a number of different installation options out and noticed that when I login to the admin page I get two servers listed:
    1) enterprise.office.tmocon.com
    2) vortex.tmocon.com

    How can I delete vortex.tmocon.com?

    Any help would be greatly appreciated. I'm desparate in trying to get the system backup and running (I'm missing many and valuable emails).

    Try to remove vortex.tmocon.com, might be looping since what you have as an Mx is local to postfix.

    Kevin,

    How do I remove vortex.tmocon.com from zimbra?

    Also, I'm supplying more info. See below:

    You should be able to delete the domain from the admin UI.

    Kevin,

    vortex is not in the domain section. It is in the servers section.
    Two servers show up here, one for enterprise.office.tmocon.com and
    one for vortex.tmocon.com. Please see attached zip file that contains
    screen shots of the admin login.

    zmprov ds SERVERNAME (to remove the server)

    You'll also want to reset the default COS mailhostpool

    zmprov mc zimbraMailHostPool ID

    Where ID is the ID of the other server from zmprov gs SERVER.

    I've executed the commands. Get a syntax error, though, on the
    reset of the COS.

    While in zmprov I get a usage error for this command:

    mc zimbraMailHostPool 9636bfbb-a0d8-4df9-9ca8-417b68f8032d
