spamlogdmanipulates the spamd(8) database in /var/db/spamd used for greylisting.
spamlogdupdates the /var/db/spamd whitelist entries whenever a connection to port 25 is logged to the pflog(4) interface. The source addresses of inbound connections are whitelisted when seen by
spamlogdto ensure that their entries in /var/db/spamd do not expire if the connecting host continues to send legitimate mail. The destination addresses of outbound connections are whitelisted when seen by
spamlogdso that replies to outbound mail may be received without initial greylisting delays. Greylisting is explained more fully in spamd(8).

spamlogdsupports realtime synchronisation of whitelist states by sending the information it updates to a number of spamd(8) daemons running on multiple machines. To enable synchronisation, use the command line option
-Yto specify the machines to which
spamlogdwill send messages when it updates the state information. For more information, see spamd(8).
