**********************************************************************
To enable spamd you need:
1) Enable spamd in /etc/rc.conf with the following line:
obspamd_enable="YES"
obspamlogd_enable="YES"
2) Configuration template is available in %%PREFIX%%/etc/spamd as
spamd.conf.sample file. Copy then to spamd.conf file and
edit to suit your needs.
3) mount fdescfs to /dev/fd with the following line in /etc/fstab
fdescfs /dev/fd fdescfs rw 0 0
4) Add following lines to the pf.conf(5)
table <spamd-white> persist
no rdr inet proto tcp from <spamd-white> to any \
port smtp
rdr pass inet proto tcp from any to any \
port smtp -> 127.0.0.1 port spamd

! changes in Ver. 4.1.x:
! - UID/GID is reserved to: _spamd:_spamd
! check the owner of /var/db/spamd
! - greylisting is now the default
! - paramer: -b is now blacklist (Ver. < 4.1.x it is bind address)
! - paramer: -l is now listen address
! - spamdb: format is now HASH, helo/ehlo is also stored in db
! convert will be done at the first start of spamd
! if you have scripts that use spamdb review this scripts
! - config files: new location is %%PREFIX%%/etc/spamd
! - spamtrapp addresses: remove the surrounding '< >' signs
! - pfspamd.sh was renamed to the obspamd
! - IPFW support (beta) added to the sources.
! See %%PREFIX%%/%%DOCSDIR%%/spamd-ipfw.txt for usage manual.

Tarpits like spamd are fake SMTP servers, which accept connections but don't
deliver mail. Instead, they keep the connections open and reply very slowly.
If the peer is patient enough to actually complete the SMTP dialogue (which
will take ten minutes or more), the tarpit returns a 'temporary error' code
(4xx), which indicates that the mail could not be delivered successfully and
that the sender should keep the mail in his queue and retry again later. If
he does, the same procedure repeats. Until, after several attempts, wasting
both his queue space and socket handles for several days, he gives up. The
resources I have to waste to do this are minimal.
Spamd is a fake sendmail(8)-like daemon which rejects false mail. It is
designed to be very efficient so that it does not slow down the receiving
machine.
If the sender is badly configured, an uncooperative recipient might actually
delay his entire queue handling for several minutes each time he connects to
the tarpit. And many spammers use badly configured open relays
spamd considers sending hosts to be of three types:
WWW: http://www.OpenBSD.org/spamd/
blacklisted hosts are redirected to spamd and tarpitted i.e. they are
communicated with very slowly to consume the sender's resources. Mail is
rejected with either a 450 or 550 error message. A blacklisted host will not
be allowed to talk to a real mail server.
whitelisted hosts do not talk to spamd. Their connections are instead sent to
a real mail server, such as sendmail(8).
greylisted hosts are redirected to spamd, but spamd has not yet decided if
they are likely spammers. They are given a temporary failure message by spamd
when they try to deliver mail.

In order to use spamd greylisting feature you have to have a mounted fdescfs(5)
at /dev/fd. This is done by adding:
fdescfs /dev/fd fdescfs rw 0 0
to /etc/fstab. You may need either a customised kernel, or kldload the fdescfs
kernel module.
