# Hooks:
# A filter can returns different values. Each return value is given a name. The
# configuration associates an action to run to a return value name.
#
# Filter:
# Current defined filter types are:
-# - rbl: match the client_address against one or more blacklist files from a rbl
+# - iplist: match the client_address against one or more blacklist files from a rbl
# Parameters:
-# - file: (non)?lock:weight:filename
-# declare a file to load. If lock is given, the blacklist is locked into the
+# - file: (no)?lock:weight:filename
+# declare a file to load. If lock is given, the klist is locked into the
# RAM. The weight is a number giving the weight of this blaclist file in the
# score of the IP
-# - soft_threshold: score (default: 0)
+# - rbldns: (no)?lock:weight:filename
+# this is an alias for file.
+# - dns: weight:hostname
+# use a rbl via DNS resolution with the given weight. If a DNS lookup error occurs
+# the IP is considered as beeing "not found".
+# - soft_threshold: score (default: 1)
# minimum score to match the soft_match return value
-# - hard_threshold: score (default: 0)
+# - hard_threshold: score (default: 1)
# minimum score to match the hard_match return value
# Return value:
# The score of a query is the sum of the weight of the blacklist it matched.
# - If the IP can not be parsed, returns error
-# - If the score is strictly greater than hard_threshold, returns hard_match
-# - If the score is strictly greater than soft_threshold, returns soft_match
+# - If no rbl was available (no file and all dns down), returns error.
+# - If the score is strictly greater >= than hard_threshold, returns hard_match
+# - If the score is strictly greater >= than soft_threshold, returns soft_match
# - Else, returns fail

+# - strlist: match strings from the query against a list of list.
+# Parameters:
+# - file: (no)?lock:(partial-)?(pre|suf)fix:weight:filename
+# declare a file to load. If lock is given, the list is locked into the
+# RAM. Prefix/Suffix is a parameter to tell the matcher which is the most
+# efficient storage order. The strings are internally stored into a trie that
+# allow high compression if a lot of prefix are shared by several strings. If
+# you choose "prefix", string are stored in the natural order in memory and
+# prefix compression is performed. If you choose "suffix", strings are stored
+# in reverse order in memory and suffix compression is performed. If you add "partial-"
+# to the match order, the entry will match if the file contains a prefix (resp. suffix)
+# of the string. The weight is a number giving the weight of this list in the string score.
+# e.g.:
+# * a file that contains ".polytechnique.org" in "partial-suffix" mode will match
+# all subdomains of "polytechnique.org".
+# * a file that contains "postmaster@" in "partial-prefix" mode will match all
+# postmaster emails.
+# * a file open without "partial-" modifier match exact strings.
+# - rbldns: (no)?lock:weight:filename
+# declare a rbldns zone file to load. This is exactly the same as file excepted that it wraps
+# parsing of hostname to split them into 2 categories:
+# * names beginning with '*' are sorted as 'domains' and are matched as suffix
+# * names starting with an alphanumirical character are sorted as 'hostnames' and are
+# process via exact matching.
+# - dns: weight:hostname
+# use a rhbl via DNS resolution with the given weight. If a DNS lookup error occurs
+# the hostname is considered as beeing "not found". This can only be used with "hostnames"
+# typed fields.
+# - soft_threshold: score (default: 1)
+# minimum score to match the soft_match return value
+# - hard_threshold: score (default: 1)
+# minimum score to match the hard_match return value
+# - fields: field_name(,field_name)*
+# list of field the match the string against.
+# currently only email OR hostname fields are supported. You MUST choose only
+# one of these types per strlist, and be carefull that the field you requested
+# are available in the protocol state you want to use this filter for.
+# * hostname fields: helo_name, client_name, reverse_client_name, sender_domain,
+# recipient_domain
+# * email fields: sender, recipient
+# No space is allowed in this parameter.
