spamd whitelist updating
spamlogd manipulates the
database in /var/db/spamd used for greylisting.
spamlogd updates the
/var/db/spamd whitelist entries whenever a
connection to port 25 is logged to the
interface. The source addresses of inbound connections are whitelisted when
spamlogd to 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
that replies to outbound mail may be received without initial greylisting
delays. Greylisting is explained more fully in
The options are as follows:
- Debugging mode.
spamlogddoes not disassociate from the controlling terminal.
- Specify that
spamlogdis only to whitelist inbound SMTP connections. By default
spamlogdwill whitelist the source of inbound SMTP connections, and the target of outbound SMTP connections.
- Specify a network interface on which packets must arrive. The default is to watch for connections logged from all interfaces.
- Specify a pflog(4) interface to listen for connection notifications. The default is to watch for connections logged on “pflog0”.
- Adjust the time for whiteexp in hours. The default is 864 hours (approximately 36 days); maximum is 2160 hours (approximately 90 days).
- Add a target to receive synchronisation messages; see SYNCHRONISATION below. This option can be specified multiple times.
It is important to log any connections to and from the real MTA in
spamlogd to update the whitelist entries.

spamlogd supports realtime synchronisation
of whitelist states by sending the information it updates to a number of
daemons running on multiple machines. To enable synchronisation, use the
