Selecting a Port for the Open/Click Tracking Server
It is preferable to run the Open/Click tracking server on port 80 because some spam filters give negative points for HTML references to unusual ports. Although it is not necessary, consider disabling other services using port 80 and assign that to the Hurricane Server Open/Click tracking server. It is important to note that both IIS and Hurricane Server enable you to specify certain IP addresses for the web server, so it is possible to have IIS listening on port 80 for one IP and for Hurricane Server to also be listening on port 80 for a different IP.
