kumo.get_memory_hard_limit
Since: Version 2026.03.04-bb93ecb1
The functionality described in this section requires version 2026.03.04-bb93ecb1 of KumoMTA, or a more recent version.
Returns the hard memory limit, or nil if none has been configured.
If your policy doesn't explicitly configure a limit via kumo.set_memory_hard_limit, whether there is a hard limit depends on the environment into which the process was spawned.
See Memory Management for a discussion on how kumomta manages memory usage.
