Messaging Gateway for Service Providers

Issue/Introduction

  • Symantec Brightmail AntiSpam (SBAS) 6.0.5 or Symantec Brightmail Message Filter (SBMF) 6.1 or 6.2 has been upgraded to Symantec Messaging Gateway for Service Providers (SMG-SP) 
  • The messages scanned by SMF have headers attached to them that are similar to the following format:

    X-Brightmail-Tracker: H4sIAAAAAAAAA+NgFrrPLMWRWlGSWpSXmKPExsXyVPEml67RpR0+BlNesVksWjuD2YHR48GmNuY

  • Previously messages scanned by SBAS/SBMF have headers attached to them that are similar to the following format:

    X-Brightmail-Tracker: AAAAAQAAAWE=

 

Cause

 The X-Brightmail-Tracker format was updated with in release of SMF 6.3.  The expected size and format of the X-Brightmail-Tracker has changed to allow much greater information to be logged for each message scanned.

Resolution

 This is expected behavior for SMF 6.3 and SMG-SP.
