Have you done any 'dig' commands to see if your domain name & A/MX records resolve correctly?
Is this PC connected directly to the internet or behind a firewall (apart from the one on the server)? Which O/S is this on? Is this a NE or OSS Zimbra server? Have you disabled any SELinux (if that's on your system)? |
This is behind a firewall. I have the appropriate ports forwarded.
SELinux and Firewall have been turned off.
I am running this on CentOS 4
Specs:
P4 3.2Ghz
512MB Ram
Dual SATA HDD
RAID 1
Single NIC
I cannot ping SBCGLOBAL.NET on my outside system at all. It comes up as:
ping: cannot resolve sbcglobal.net: Unknown host.
On my zcs server, it comes up as:
[root@zcs etc]# ping sbcglobal.net
PING sbcglobal.net.sitediscovery.com (75.31.55.210) 56(84) bytes of data.
64 bytes from adsl-75-31-55-210.dsl.scrm01.sbcglobal.net (75.31.55.210): icmp_seq=0 ttl=64 time=0.313 ms
Why is my zcs server resolving the entire sbcglobal.net domain to my external ip?
