  1. Overview of this Critical Patch Release
  ======================================================================
     This critical patch resolves the following issue:

     Issue:    In InterScan Messaging Virtual Appliance (IMSVA) versions 
               released before version 9.0, when an administrator 
               configures the "Administration > SMTP Routing > Message 
               Delivery" settings and input a fully-qualified domain 
               name (FQDN) for the target "Server address", Postfix will 
               try to query the MX record of the FQDN so that: 

               - if the MX record exists, IMSVA will deliver the mail 
                 to the MX record. 
                 
               - if the MX record does not exist, IMSVA will try to
                 query the corresponding A record and deliver the
                 mail to the A record.

               The IMSVA 9.0 GM build queries only the A record 
               of the FQDN. This may cause email delivery issues when
               delivering messages between different IMSVA versions.
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution: This critical patch prevents delivery issues by making 
               the following changes:

               - If a user imports configuration files from versions
                 older than version 9.0 GM build, it will keep the 
                 same behavior as the previous version.

               - If a user adds a new delivery setting in IMSVA 9.0, 
                 the user has the option to configure IMSVA to query
                 the MX record or A record.
                        
     Note:     This solution will be added to the repacked version of 
               IMSVA 9.0 GM build and in Hot Fix 1504 so that upgrading 
               to any of these versions also resolves the issue.

               Refer to "Known Issues" for more information on a known
               Issue related to this solution.
