NAME    [Toc]    [Back]

     spamlogd - spamd whitelist updating daemon

SYNOPSIS    [Toc]    [Back]

     spamlogd [-I] [-i interface]

DESCRIPTION    [Toc]    [Back]

     spamlogd manipulates the spamd(8) database in  /var/db/spamd
used for
     spamd(8)  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 (see GREYLISTING in spamd(8)).

     The options are as follows:

     -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

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

     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

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

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