I have the following problem that on reboot the vps myserver reset his hostname.
now will explain
i'm admin of the hard node and the vps
virtualization with openvz virtuozzo
vps is with cPanel 11.24.5-C38506 - WHM 11.24.2 - X 3.9
CENTOS 5.3 x86_64 virtuozzo.
In the config file of the ve hostname is set to as should be FQDN
and each time when i restart the vps it's hostname change host1 not FQDN
and mail server begin to send email with hello of host1 not
and the messages come back "mail delivery system..Helo command rejected: need fully-qualified hostname".
What I do at this time;
1.from hard node redefine the FQDN host name and after restart nothing;
2.try to changed layout in /etc/hosts from ip host1 to ip host1 because on reboot it reseting to ip host1
this resolve problem with emails until the next reboot
3.change hostname in /etc/sysconfig/network to FQDN
and make update of license key -- nothing reboot=reset=mail problem WHM of the vps change the hostname from host1 to as should be FQDN,
ask me to enter A record in dns zone, it exist and temporarily solve the problem with the Post until the next reboot.

where is the problem.

On a VPS you cannot change the hostname. It should be changed on the hardware node. So ask your provider.
