I caught it after I did it, that's the /etc/host.conf

/etc/host should be:

127.0.0.1	localhost localhost.localdomain localhost4
localhost4.localdomain4
192.168.1.110	ts130.palmettodomains.com	ts130
192.168.1.110 mail.palmettodomains.com mail

# ::1         localhost localhost.localdomain localhost6
localhost6.localdomain6
192.168.1.102	edukes1.palmettodomains.com edukes1
192.168.1.105	hp8200.palmettodomains.com hp8200

CentOS created the file

I do have named running but I can remove the 127.0.0.1
