Here are my resolv.conf and hosts files now:
[root@mail ~]# cat /etc/resolv.conf
nameserver 67.207.128.5
nameserver 67.207.128.4
[root@mail ~]# cat /etc/host
host.conf hosts hosts.allow hosts.deny
[root@mail ~]# cat /etc/hosts
127.0.0.1 mail.ofsloans.com localhost
209.20.66.252 mail.ofsloans.com

After the reboot:
[zimbra@mail ~]$ zmcontrol status
