kumo.aaa.set_check_cache_ttl

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.

kumo.on('pre_init', function()
  kumo.aaa.set_check_cache_ttl '5 minutes'
end)

This function sets the Time To Live (TTL) duration for the ACL-check cache.

The ACL-check cache is used to cache the overall status of an authorization check for a given resource, privilege, and auth_info combination.

The default duration is 5 minutes.

Note

This function is intended to be used in pre_init as shown above. It can be called at any time, but reducing the TTL after init will not automatically trigger a cache eviction.
