spamd.conf - configuration file read by spamd-setup(8) for
spamd(8)
spamd.conf
The spamd.conf file is read by spamd-setup(8) to configure
blacklists and
whitelists with corresponding pf(4) table entries for
spamd(8).
spamd.conf follows the syntax of configuration databases as
documented in
getcap(3). Example:
all: :spews1:white:myblack:
spews1: :black:
:msg="SPAM. Your address %A is in the spews
level 1 database0ee http://www.spews.org/ask.cgi?x=%A0:
:method=http:
:file=www.spews.org/spews_list_level1.txt:
white: :white:
:method=file: :file=/var/mail/mywhite.txt:
myblack: :black:
:msg=/var/mail/myblackmsg.txt: :method=file:
:file=/var/mail/myblack.txt:
The default configuration file must include the entry all
which specifies
the order in which named blacklists and whitelists are to be
applied.
The addresses in a whitelist are removed from the preceding
blacklist.
In the above example, if the address was present in all
three lists,
blacklists spews1 and myblack, as well as whitelist white,
the address
would be removed from blacklist spews1 by the subsequent
white whitelist.
However, the address would not be removed from the myblack
blacklist. To
remove all the addresses in white from myblack, the configuration
all: :spews1:white:myblack:white:
would be used instead.
Blacklists and whitelists are then constructed by name;
blacklists are
identified by the capability black, and whitelists by the
capability
white.
The source of the addresses for blacklists and whitelists is
specified
using the method and file capability entries.
method specifies the method by which to retrieve a file containing a list
of addresses that consist of the blacklist or whitelist, and
may be http,
ftp, file or exec. The methods http, ftp and file capabilities will make
spamd.conf retrieve a list of addresses specified in the location in the
file capability for the list. The exec capability will make
spamd.conf
spawn the program with arguments indicated in the file capability for the
list, and reads a list of addresses from the output of the
program.
The format of the list of addresses is expected to consist
of one network
block or address per line (optionally followed by a space
and text that
is ignored). Comment lines beginning with # are ignored.
Network blocks
may be specified in any of the formats as in the following
example:
# CIDR format
192.168.20.0/24
# A start - end range
192.168.21.0 - 192.168.21.255
# As a single IP address
192.168.23.1
Each blacklist must include a message, specified in the msg
capability as
a string. If the msg string is enclosed in double quotes,
the characters
in the quoted string are escaped as specified in getcap(3)
with the exception
that a colon (:) is allowed in the quoted string.
The resulting
string is used as the message. Alternatively, if the msg
string is not
specified in quotes, it is assumed to be a local filename
from which the
message text may be read.
The message is configured in spamd(8) to be displayed in the
SMTP dialogue
to any connections that match addresses in the blacklist. The sequence
sequence %% will produce a single % in the output, and the
sequence %A
will be expanded in the message by spamd(8) to display the
connecting IP
address in the output.
