Record ptr reverse dns

i have this problem with reverse dns on OCI

i must change the ptr to omargaiani.com …or i can solve in another way
without open a ticket with OCI

v-change-sys-hostname newhostname.com to update the hostname it is used for the help name look up if I am right.

i m sorry but i must run : v-change-sys-hostname newhostname.com
or i change it in the exim4.conf.4.94.template
becouse the host name in the instance is correct configurated

v-change-dus-hostname should be enough

when i instal hestia i have done the hostname like in this message of the forum

cheers
Omar
