SPAMLOGD(8)		 BSD System Manager's Manual		   SPAMLOGD(8)

NAME
     spamlogd - spamd whitelist updating daemon

SYNOPSIS
     spamlogd [-DI] [-i interface] [-l pflog_interface] [-Y synctarget]

DESCRIPTION
     spamlogd manipulates the spamd(8) database in /var/db/spamd used for
     greylisting. spamlogd updates the /var/db/spamd whitelist entries whenev-
     er a connection to port 25 is logged to the pflog(4) interface. The
     source addresses of inbound connections are whitelisted when seen by
     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 spamlogd
     so that replies to outbound mail may be received without initial greyl-
     isting delays. Greylisting is explained more fully in spamd(8).

     The options are as follows:

     -D	     Debugging mode. spamlogd does not disassociate from the control-
	     ling terminal.

     -I	     Specify that spamlogd is only to whitelist inbound SMTP connec-
	     tions. By default spamlogd will whitelist the source of inbound
	     SMTP connections, and the target of outbound SMTP connections.

     -i interface
	     Specify a network interface on which packets must arrive. The de-
	     fault is to watch for connections logged from any interfaces.

     -l pflog_interface
	     Specify a pflog(4) interface to listen for connection notifica-
	     tions. The default is to watch for connections logged on
	     "pflog0".

     -Y synctarget
	     Add a target to receive synchronisation messages; see
	     SYNCHRONISATION below. This option can be specified multiple
	     times.

     It is important to be sure to log any connections to and from your real
     MTA in order for spamlogd to update the whitelist entries. An example
     pf.conf(5) configuration for logging such connections is as follows:

	   EXT_IF = "fxp0"
	   MAILHOSTS = "{129.128.11.10, 129.128.11.43}"
	   pass in log on $EXT_IF inet proto tcp to $MAILHOSTS \
		   port smtp
	   pass out log on $EXT_IF inet proto tcp from $MAILHOSTS \
		   to any port smtp

     spamlogd sends log messages to syslogd(8) using facility daemon. spamlogd
     will log each connection it sees at level LOG_DEBUG.

SYNCHRONISATION
     spamlogd supports 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 -Y to
     specify the machines to which spamlogd will send messages when it updates
     the state information. For more information see spamd(8)
