Set the proper hostname using hostnamectl command if it is not set.

mail.hackthesec.co.in

Update the /etc/hosts file

127.0.0.1 mail.hackthesec.co.in localhost.localdomain localhost

Disable Selinux

[root@hackthesec ~]# setenforce 0

Edit the file /etc/sysconfig/selinux , set the parameter “SELINUX=disabled” , Reboot the server to disable selinux completely.
