    Yup, I'd say there's at least one install question a day on DNS & MX records.

    Have have 'em read up on NAT as well (Network Address Translation aka Network Masquerading/IP Masquerading).

    Default Progress?

    So the back tick command gave me a "Command not found" error.
    But the mx command gave us this.

    ;; QUESTION SECTION:
    ;mail.mpseast.com. IN MX

    ;; ANSWER SECTION:
    mail.mpseast.com. 3600 IN MX 10 mail.mpseast.com.

    ;; AUTHORITY SECTION:
    mpseast.com. 19201 IN NS dns3.valueweb.com.
    mpseast.com. 19201 IN NS dns1.valueweb.com.
    mpseast.com. 19201 IN NS dns2.valueweb.com.

    ;; ADDITIONAL SECTION:
    mail.mpseast.com. 1609 IN A 170.211.174.36
    dns1.valueweb.com. 149228 IN A 207.36.172.5
    dns2.valueweb.com. 149228 IN A 207.36.173.5
    dns3.valueweb.com. 153700 IN A 207.36.174.5

    Both, Postfix and zmapchectl aren't running.

    Your external (what you posted) looks fine.

    Is the only IP assigned to the box 170.211.174.36? or do you have a private ip?-for which you need the machine to resolve lookups from the local dns (the bind articles or use the 2 dns boxes you already have) and get a private ip, usually like the below:
    10.0.0.0 - 10.255.255.255
    172.16.0.0 - 172.31.255.255
    192.168.0.0 - 192.168.255.255
    (assigned via dchp or manually set on every computer)

    170.211.174.36 = router ip (mpseast.com & mail.mpseast.com point to this ip)
    192.168.1.15 = linux box (zimbra box) ip
    192.168.1.2= Domain Controller/IIS/DNS

    So at this point everythingis correct, we just need to work on DNS? Should we load bind on the linux box or try to use the windows DNS? Which would be easier?

    Since the DNS on the windows network is already running wouldn't we just have to make some entry changes? Maybe set up a reverse lookup zone?

    Yup, if your able to manage the 192.168.1.2 DNS box, give it an entry for mail.mpseast.com pointing to 192.168.1.15

    on the zimbra box- make sure your /etc/resolv.conf (or just see dns settings in your GUI) are set to use the internal 192.168.1.2 box for dns lookups

    set your /etc/hosts to:
    127.0.0.1 localhost.localdomain localhost
    192.168.1.15 mail.mpseast.com mail

    /etc/hostname (or again use your gui):
    mail.mpseast.com

    if the hostname has changed/was different-easiest to just do a fresh uninstall/reinstall of zimbra (note: you shouldn't have the proxy (perdition) service installed at all on a single server setup)

    Once zimbra is fired up, be sure 'enable dns lookups' is check in both the server & global settings mta tabs (it probably will already be)

    These should return the private ip's:
    host -t mx domain
    or
    host `hostname` <-- backticks not single quotes

    Later on (well you might as well set this anyway)
    If you have trouble with outgoing mail & see some 554 'relay access denied' errors:
    zmprov gs server.domain.com | grep zimbraMtaMyNetworks
    zimbraMtaMyNetworks should have 127.0.0.0/8 192.168.1.0/24

    I set a pointer of 192.168.1.15 mail.mpseast.com in the reverse lookup zone for 192.168.1.x on the windows dns server. Is there anything else I have to do. After doing this we decided to reinstall zimbra hoping that the dns and hosts issues would be taken care of. Here is the error we recieved while installing.

    Suggestions?


    Setting defaults... MX: mail.mpseast.com (170.211.174.36)

    Interface: 192.168.1.15
    Interface: 127.0.0.1
    170.211.174.36
    170.211.174.36


    DNS ERROR - none of the MX records for mail.mpseast.com
    resolve to this host
    Change domain name? [Yes]

    Ah, I see how you could have interpreted the 'yep' (especially after your edit)
    Not not reverse, regular A & MX
    You still resolving to the outside ip-as shown by the first line you posted...

    Post the contents of all the files listed in my prior post, as well as your ethernet settings usually somewhere in the following:
    ifconfig
    system-config-network
    /etc/sysconfig/network

    Not not reverse, regular A & MX

    Not not ? i am confused. Do you want me to try to set up an A and Mx record? Would that be in forward or reverse zone?

    Thank you for the help. I know it is frustrating.

    Foward, so that when searching the name you get the ip aka: name>ip (like what your webbrowser does)
    (You can leave the reverse that you've already setup as is-it won't hurt. aka: ip>hostname)

    for now remove:
    nameserver 65.64.8.3 (not saying that you can't use it later-but for now we want to only use your local dns box just to make sure this works)
