siv_throttle_cache_size — set the maximum number of named throttles
siv_throttle_cache_size = 1000
This option sets the maximum number of named throttles created by the Sieve command ec_throttle_create and by Lua scripts. If you try to create more throttles than this value, throttles created earlier will be destroyed. Prior to version 3.0.24, the value of this option defaults to
100. This option should only be changed if you need to use more than 100 named throttles.
**Configuration Change. ** As of version 3.0.24, the default value for this option has been increased to
1000. This was done because Adaptive Delivery makes heavy use of throttles.
siv_throttle_cache_size is valid in the global scope.
