I setup reverse dns from my vps provider. some mail test sites said that my ptr record which is mail.cembol.com is not the same mail domain cembol.com so I decided to change my mx record to from mail.cembol.com to cembol.com. mx record do not update to the dns servers anymore. here is my syslog; Code: Feb 24 12:07:02 cembol systemd[1]: Reloading BIND Domain Name Server.
