ZixGateway Domains

Required, User-defined

These parameters define the email domains for which the ZixGateway will encrypt/decrypt email 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 ZixVPM domain key in ZixGateway Manager to deploy properly. A ZIxVPM 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 zixvpm@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 ZixVPM domain in ZixGateway Manager and name it zixgatewayinbound.zixcustomer.com to properly import you domain key.

Use the ZixGateway Domains area to add ZixGateway domains. Initially, the table is empty and displays No Existing Domains. Every one of the email domains and subdomains that ZixGateway handles must be defined in this table.

Note: Unlike cluster names, a domain name is not arbitrary. The following are required 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

To define the email domains:

1. Consult the list of your email domains that you prepared prior to configuration.
2. Mark each of the email domains that you want handled by this cluster.
3. Enter the first of these email domains into the Add field and prepend it with zixvpm.
   
   For example, to add the zixcustomer.com domain, enter “zixvpm.zixcustomer.com.”
4. Click Add.
5. Repeat steps 3 and 4 for each of your email domains in the ZixGateway Domains table.
   
   Note: At this point, the Status flag next to each of your email domains is red and displays needs key file.  This is a reminder to associate an appropriate encryption key file with each email domain. You must provide these associations before the configuration is deployed to the cluster.
6. Click  for the first email domain in the table.
   
   The ZixGateway Domain Name screen displays.
   
   Define three values in this area: Key File, Password and Mail Host.
   
   ZixSignature Manager set the Key File name when you created your gateway key during installation. The Key File name is a hash of the email domain name in the form em_<email_domain_hash>.zky and is displayed on the light gray area in the middle of the dialog.
7. Do one of the following to specify the location of the original of this key file.

• Type the location in the Key File field, OR

• Navigate to this file using the Browse button.

In the Windows NT/2000/XP family, the key files are located in:

C:\Documents and Settings\<username>\Application Data\Zixit\

• Find the file matching the Key File, select it, and click OK.

8. Enter the passphrase for this key file into the Password field.
   
   The passphrase is the string of characters that you specified when you created the gateway key file in ZixSignature Manager.
9. In the Mail Host field, enter the domain name or IP address of the email server that is the host for this email domain. ZixGateway (as a mail relay) uses the address as the destination for incoming email addressed to this email domain after decryption, if necessary.
   
   If ZixGateway is not connected directly to the email server, enter the IP address of the first intervening server. For example, if you have an anti-virus server between the ZixGateway and the email server, enter the IP address of the anti-virus server.
10. Click Apply.
    
    You have defined the first domain.
    The Status flag in the first row of the ZixGateway Domains area should now be green and display has key file.
11. Repeat the steps above to define other domains until the status flags are all green.

To delete an email domain

1. Select the Configure Sever tab.
2. Select the System tab.
3. Click  in the row in the ZixGateway Domains area for the domain to be deleted. 
   
   ZixGateway Manager asks you to confirm the deletion. 
4. Click OK.

The ZixGateway Domains area updates, showing only the remaining domains.
