Hello all, I'm running postfix postfix-3.3.1 on FreeBSD 11.1-RELEASE.
For quite a long time I've used a persistent postscreen_cache file: postscreen_cache_map = btree:/var/db/postfix/postscreen_cache postscreen_cache_retention_time = 90d The postscreen_cache.db file is there and seems to be updated. A few times in the past I've noticed that, after rebooting the server, IP addresses that are in the postscreen_cache.db are bounced with a "Service currently unavailable". I decided to check one of these today after a reboot and found that the dates and times for the IP appear to be within the 90 day retention period: Using postmap -s btree:/var/db/postfix/postscreen_cache: 203.38.21.10 1533826625;1533740285;1534656999;1534656999;1534656999 1533826625 2018-08-09 14:57:05 1533740285 2018-08-08 14:58:05 1534656999 2018-08-19 05:36:39 1534656999 2018-08-19 05:36:39 1534656999 2018-08-19 05:36:39 (Although I have no idea what these dates and times represent.) Have I misunderstood the purpose and/or use of the persistent cache? Thanks
