Your Keyfax web server IP address may change for example if you move Keyfax between different cloud regions. Whenever your Keyfax web servers internal and / or external IP address changes you should consider the following…

* Ensure IP addresses within Connection & Rely restrictions within IIS 6.0 Manager > SMTP Virtual Serer properties are updated to use the latest IP address
* Ensure IP addresses are updated within any IIS bindings if there is more than 1 IP address used by the web server.
* Ensure any internal and / or external DNS records are updated to point to the new / updated Keyfax web servers IP address.
