The IMAP protocol server is disabled by default. You
  need to enable the IMAP protocol server to start interaction between the
  email client and the SkyVault
  repository.
    - Open the SkyVault-global.properties file.
 - 
        Add the following sample configuration properties:
        
imap.server.enabled=true imap.server.port=143 imap.server.host=x.x.x.x
Note: The x.x.x.x value is the IP address (or corresponding DNS name) of your external IP interface. Do not use localhost as the imap.server.host property value.The default port value is 143, which will be used even if you do not add the imap.server.port property. You will need to add in this property if you require a different port number.
 - Restart the SkyVault server.
 
Once the SkyVault
      server has restarted, the new configuration will take effect. Since the IMAP server has only
      one instance, make your configuration changes to the
        SkyVault-global.properties file. You can also create a file called
        <extension>\subsystems\imap\default\default and add your changes for
      the IMAP subsystem configuration.
