Issue



Do the Symantec Mail Security products work with daylight saving time (DST)?


Solution



Symantec Mail Security products obtain time information in one of three ways:

    • From the operating system
    • From Java Runtime Environment (JRE)
    • From software updates


As long as the operating system, JRE, or the appliance software are updated to support DST, the Mail Security products work correctly with DST.

Products that obtain time from the operating system

    • Symantec Hosted Mail Security
    • Symantec Mail Security for Microsoft Exchange
    • Symantec Mail Security for Domino
    • Symantec Mail Security 4.1 for SMTP
    • Symantec Brightmail AntiSpam 4.0.x


Please refer to the following for operating system/platform updates or information


Products that obtain time from JRE

    • Symantec Brightmail AntiSpam 6.0.x
    • Symantec Mail Security 5.0 for SMTP


Refer to the following for JRE updates or information


Products that require software updates

    • Symantec Traffic Shaper
      Requires software version 5.1.9-1 or later. Please use the Software Updates feature on the appliance interface to make any necessary updates.
    • Symantec Brightmail Gateway
      Requires software version 5.0.0-30 or later. Please read the article "Applying software updates to Symantec Mail Security 8200/8300 Series appliance" at TECH85281 to make any necessary updates.
