    Default :) strange DNS issue !!! -elligible-

    sorry for the first post...

    well I am behind a firewall, but I am in a DMZ zone where I have everything routed to me.
    Since I have an internal address range for the DMZ (192.168.1....) , and I have no internal DNS. I use my ISP's DNS. I think Zimbra is trying to reslove my 192.168.1.120 address and it gets nothing so it can't do a reverse on my address.

    is there a awork around without having a DNS internally ? would changing the address of my host in /etc/hosts from 192.168.1.120 to the external one work ?
    does postfox takes the address from ifconfig ... I am stuckk.....

    Thanks

    Does your ISP have a mail server you can use to relay mail? If so you should point to that and just turn off DNS lookups in Zimbra's postfix.

    not sure they do.

    I think will just expose my machine for testing. I am running RHEL 4 and the latest network edition.

    but are there any work arounds for the DNS entry, so that when postfix does a reverse lookup at the end of the install on my FQDN it gets the correct domain ?

    since I am using this behind a cheap router (lynksys) I am testing from home, is there a recommendation on what setup to use with iptables since I will swith the cheap router with an IPcop ?

    any ideas ?

    It's pretty simple. If DNS is ON you have to have valid internal and external entries. If DNS is off you use your ISP. The only other option is that you turn DNS on and run your own local DNS server.
