kumo.get_memory_soft_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 soft memory limit, or nil if none has been configured.
If your policy doesn't explicitly configure hard/soft limits, whether there is a default soft limit depends on the environment into which the process was spawned.
