Please do not open the postscreen cache through the proxymap daemon. It cannot meet postscreen performance requirements. Also, there is no need to share lmdb maps this way. Lmdb maps are already multi-writer safe as long as you respect the locking protocol (https://www.postfix.org/lmdb_table.5.html section "SYNCHRONIZATION"). Yes, proxymap should not panic, but it should not be used here anyway. > Mar 17 13:24:48 servername postfix/postscreen[164]: fatal: watchdog timeout That's the default "postscreen_watchdog_timeout = 10s", timing out because of the proxymap service failure.
