In my logs I see postscreen cache cleanups
postfix/postscreen[18826]: cache
btree:/var/lib/postfix/postscreen_cache full cleanup: retained=224 dropped=12
entries
It looks like it's happening because they're 'full' at the time.
Under "CACHE CONTROLS" & "RESOURCE CONTROLS" @
http://www.postfix.org/postscreen.8.html, I don't see a param to increase the
cache size.
Does the cache need to b increased, so performance doesn't suffer?
What's the parameter to control that?
Also in the docs I see
postscreen_cache_map (default: btree:$data_directory/postscreen_cache)
Is there any advantage/harm in using lmdb here, instead of btree? I'm already
using lmdb as default DB type for most other !pcre tables.
