bounce_cache_ttl — set the maximum TTL for the bounce classification cache


bounce_cache_size = 300


**Configuration Change. ** This feature is available as of version 3.6.9.

bounce_cache_size and bounce_cache_ttl together set the maximum size and TTL of the bounce_classify and bounce_classify2 caches. These caches are used to cache bounce classifications. It should not normally be necessary to modify these values.

The default value for this option is 60.


bounce_cache_ttl is valid in the global scope.
