Hello Zimbra Customers, Partners & Friends,

  • Oracle 6 End of life occurred October 2020

If there is an issue related to a bug or operating system, the system will need to be upgraded to a supported version to continue troubleshooting.

Zimbra Support recommends all customers who are running these operating systems take immediate actions to upgrade all production systems to ensure no interruption in your support services.
