SPAMD.CONF(5)             NetBSD File Formats Manual             SPAMD.CONF(5)

NAME
     spamd.conf -- configuration file read by spamd-setup(8) for spamd(8)

SYNOPSIS
     spamd.conf

DESCRIPTION
     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 database\nsee http://www.spews.org/ask.cgi?x=%A\n":\
                   :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 result-
     ing 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 dia-
     logue to any connections that match addresses in the blacklist.  The
     sequence \" in the message will produce a double quote in the output.
     The 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.
