Each setting applies to every server included in the Configuration Settings document. Therefore, you need multiple Configuration documents if you need different settings for specific servers. For example, if your Domino domain includes three geographic locations, you may want a Configuration Settings document for each location. You can create groups that include all the servers in the specific location and use the location as the group name.
To specify additional restrictions for a server that is included in a group, create a separate Configuration Settings document for the specific server. For example, assume you have a Configuration Settings document for a group of servers or for all servers. The executives in your organization have their own mail server and require different settings. You will need to create a Configuration Settings document for the specific server. The document that is most specific (in terms of which servers it applies to) will take precedence.
Each server checks the Configuration Settings documents in the following order -- a document specific to the server, then a group document for any group the server is in, and then for the default document. If there are multiple Configuration documents for groups containing the same server, the results are undefined. For example, you could have a server ServerA, and two groups named Group1 and Group2 that both contain ServerA. If you create a Configuration Settings document naming ServerA, all settings that are set in that document are used by ServerA, but if there are settings that are not defined in that document, then the Configuration documents defined for Group1 and Group2 are examined for those settings. However any settings that were defined in the ServerA document will not be examined in the Group1 and Group2 documents. If after examining the Group1 and Group2 documents there are still settings that do not have values defined, the default settings apply.
Note Use fully qualified host names in fields on the Configuration Settings document instead of IP addresses. While IP addresses will work and are fully supported, using host names ensures that you won't need to change a server entry in the event that a subnet change requires a change to the server's IP address. You can change the server's record once in the Domain Name Service (DNS) rather than having to search through the Domino Directory to find every instance where the server is referenced.
