     spamd.conf	-- spamd configuration file


     The spamd.conf file is read by spamd-setup(8) to configure	blacklists for
     spamd(8).	Blacklists are lists of	addresses of likely spammers.  Mail
     from these	addresses never	reaches	the actual mail	server,	but is instead
     redirected	to spamd(8) and	tarpitted.

     spamd.conf	follows	the syntax of configuration databases as documented in
     getcap(3).	 Here is an example:


		   :msg="SPAM. Your address %A is in the spews\
		   level 1 database\nsee\n":\



     The default configuration file must include the entry all,	which speci-
     fies the order in which lists are to be applied.  Lists are constructed
     by	name: blacklists are identified	by the capability :black:.  If a list
     is	instead	given the :white: capability, addresses	in it will not be
     blacklisted.  The addresses in such a list	are removed from the preceding

     In	the above example, if an address was present in	all three lists,
     blacklists	spews1 and myblack, as well as the exceptions list override,
     the address would be removed from list spews1 by the subsequent override
     list.  However, the address would not be removed from the myblack list.
     To	remove all the addresses in override from myblack, the following con-
     figuration	would be used instead:


     The source	of the addresses for lists is specified	using the method and
     file capability entries.

     method specifies the method by which to retrieve a	file containing	a list
     of	addresses and may be one of http, ftp, file, or	exec.  The http, ftp,
     and file methods will make	spamd.conf retrieve the	file from the location
     specified by the file capability.	The exec method	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
	   # A start - end range	-
	   # As	a single IP address

     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 ex-
     ception 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 dia-
     logue to any connections that match addresses in the blacklist.  The se-
     quence \" 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.

     ftp(1), spamd(8), spamd-setup(8)
