These parameters define the email domains for which ZixGateway will encrypt/decrypt messages.
Your organization may have one or hundreds of email domains. You may want all or just some of these email domains to be handled by ZixGateway. In addition, you may want different subsets of your email domains handled by distinct ZixGateway clusters.
ZixGateway Inbound customers are required to set up one unique ZixGateway domain key in ZixGateway Manager to deploy properly. A ZixGateway domain key is created in ZixSignature Manager and then imported into ZixGateway Manager. The domain key you create in ZixSignature Manager must be in the format zixvpmgateway@zixgatewayinbound.zixcustomer.com.
The purpose of the domain key with ZixGateway Inbound is not used for encryption but as a place holder for proper ZixGateway Inbound deployment.
ZixCorp requires that ZixGateway Inbound customers add a ZixGateway domain in ZixGateway Manager and name it zixgatewayinbound.zixcustomer.com to properly import your domain key.
Use the ZixGateway Domains section to add ZixGateway domains. Initially, the table is empty and displays No Existing Domains. Every email domain and subdomain that ZixGateway handles must be defined in this table.
Unlike cluster names, a domain name is not arbitrary. Requirements are as follows before the configuration can be deployed to the cluster:
| • | Fully-qualified domain name for one of your corporate email domains |
| • | Begin with zixvpm. (added to the beginning of the domain name) |
| • | Assigned a ZixMail private key file |
