    These are my first real linux installs so bear with me...

    My internal network (say 10 dot) has my sole exchange 2003 server. It is published to the DMZ via ISA 2006. I just added a spamsnake server to the DMZ and replaced the DNS box with ubuntu and bind9 as well. So all 3 sit with outside world ip's and everything is great until I email certain servers. Failed RNDS on is the reply. I did not setup the dns right I think. So here is the setup:



    My reverse lookup zone shows the same.
    btw subnet is if you wonder.

    So what am I missing? Is the problem DNS, spamsnake config or ISA?

    Thank you for any help

    Why are you using private IPs in your zones?

    Sorry about the confusion. The 192 range is just a place holder. I am using real external IP's for those addresses.

    Is your DNS server authoritative for your domain, or is it maybe another name server?

    Nope, I control the only DNS entries. I even double checked from home. As an experiment I made an additional MX record: IN MX 10 IN MX 20
    but still the error... I am beginning to think the problem is a dns issue. Bind is still very new to me.

    vi /etc/bind/zones/
    @ IN SOA (

    IN NS
    162 IN PTR
    163 IN PTR
    164 IN PTR

    I tried to copy everything down to the last dot. If anyone sees anything please let me know.

    Falko, thank you for the help so far...

    I think you've missed the dot at the end. It shold rather look like this:
    Code:	IN	MX	10[B][COLOR="Red"].[/COLOR][/B]	IN	MX	20[B][COLOR="Red"].[/COLOR][/B]
