Technical Tip: FortiMail HA synchronization interval
Description
This article describes that in a FortiMail in HA mode when a configuration is updated on the Primary unit, the Secondary unit is immediately updated as well. This is valid for both, Active-Passive HA and Config-only HA.
Additionally, units in Active-Passive HA can synchronize data directories - system quarantine, email archives, email users’ mailboxes (server mode only), preferences, and per-recipient quarantines).
The interval for this synchronization is up to 20 minutes on units running firmware v5.0.3 and higher. For units running firmware prior to v5.0.3, this interval is 20-40 minutes.

Scope
FortiMail.
Solution
The data directory synchronization can be enabled in System -> High Availability -> Configuration.
It can also be synchronized through the CLI:
config system ha
set mail-data-sync enable
end
set mail-data-sync enable
end
This setting must be enabled on both cluster nodes for the feature to work.
