SPAMLOGD(8) OpenBSD System Manager's Manual SPAMLOGD(8)NAMEspamlogd - spamd whitelist updating daemon
SYNOPSISspamlogd [-DI] [-i interface] [-l pflog_interface] [-Y synctarget]
DESCRIPTIONspamlogd manipulates the spamd(8) 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 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
greylisting delays. Greylisting is explained more fully in spamd(8).
The options are as follows:
-D Debugging mode. spamlogd does not disassociate from the
controlling terminal.
-I Specify that spamlogd is only to whitelist inbound SMTP
connections. 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
default is to watch for connections logged from all interfaces.
-l pflog_interface
Specify a pflog(4) interface to listen for connection
notifications. 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 log any connections to and from the real MTA in order
for spamlogd to update the whitelist entries. See spamd(8) for an
example ruleset for logging such connections.
spamlogd sends log messages to syslogd(8) using facility daemon.
spamlogd will log each connection it sees at level LOG_DEBUG.
SYNCHRONISATIONspamlogd 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
option -Y to specify the machines to which spamlogd will send messages
when it updates the state information. For more information, see
spamd(8).
