Article ID: 171821


Updated On:


Messaging Gateway


  • A Symantec Messaging Gateway (SMG) cannot update to 10.6.5-1 or later.
  • The upgrade option is greyed out.


This issue is caused with SMG appliance installations that are no longer under warranty from Dell, as of June 1, 2018.

SMG 10.6.5-1 and later have new minimum requirements. The hardware that is no longer supported is listed in the SMG Release Notes.



There are three possibile solutions to this issue:

  1. Continue to use SMG version 10.6.4-3 on the hardware. DMARC will not be supported. (No longer recommended as of the release of SMG 10.6.6-4, due to CVE concerns.
  2. Purchase new appliance from a Symantec vendor.
  3. Install SMG on a virtual machine. VMWare ESX and Hyper-V installations are supported by Symantec. For more information, please refer to the Administration Guide for SMG 10.6.5.
