If you are trying to configure Kerio Connect to use a different DNS server, separate from the one used by the operating system, this article is aimed at clarifying this topic!
Kerio Connect does not have it's own internal DNS server, and instead relies on the DNS server of the hosting operating system. Because of this, it is not possible to set up an alternative DNS server for Kerio Connect to use specifically.
Depending on the DNS server of the operating system, you may be able to implement some conditional DNS forwarding, however, this would be out of support scope.
While it may be desirable to use a different DNS server for specific tasks, Kerio Connect does not support this functionality. The DNS server used by Kerio Connect is determined by the operating system settings and cannot be changed independently.
Can I use a different DNS server for Kerio Connect than the one used by my operating system?
No, Kerio Connect does not support the use of a different DNS server than the one used by the operating system.
Is there a workaround to use a different DNS server with Kerio Connect specifically?
The operating system DNS server may allow for custom DNS forwarding, however, configuring it is out of support scope.
Can I change the DNS server settings in my operating system to affect Kerio Connect?
Yes, changing the DNS server in your operating system settings will affect the DNS server used by Kerio Connect.
