NAME

opendkim-spam - DKIM filter spam correlation tool

SYNOPSIS

opendkim-spam [options]

DESCRIPTION

opendkim-spam accepts a regular format message (RFC5322) on standard input and uses it to update a local SQL database being updated by opendkim(8) with an indiciation that a user believes the input message is spam or otherwise abusive. This feedback is important input toward developing DKIM-based domain reputation systems. The tool is intended to be used directly from within shell-based mail readers such as alpine(1) or mutt(1) using a "pipe" command, which feeds the message being read to the specified program. This tool is experimental. If the experiment proves useful, the feedback could be used as an input stream to a larger-scale collaborative feedback system that can be used to iden‐ tify sources of signed mail that have good reputations.

OPTIONS

-b backend Specifies the style of backend database in use. The default is "yes". -c file Names a configuration file from which operating parameters will be read. The con‐ figuration file contains entries of the form "key value", one per line. Empty lines or lines beginning with a hash ("#") character are ignored. Command line equivalents for the configuration file are available as runtime overrides. The default configuration file location is /etc/opendkim-spam.conf. See the CONFIGURA‐ TION FILE section for a list of known values. -f Run in the foreground rather than executing as a background process. Intended mainly for debugging. -d name Indicates the name of the database to be accessed. The default is "opendkim". -h host Specifies the host where the database server is running. The default is "local‐ host". -o file Writes an update record to an OpenDKIM statistics file rather than directly to a database. There is no default. Note that if this option is used, all database- specific options are ignored. -p password Specifies the password to be used when authenticating to the database. The default is "opendkim". -P port Specifies the port number where the database server is listening. The default depends on which backend is in use. -r reporter Provides the name of the site reporting the spam. If not provided, an attempt will be made to extract this information from the topmost Received header field from the input message. -s column Names the database column whose value should be incremented as a result of this user action. The default is "spam". -u user Identifies the database user to be used when connecting to the database. The default is "opendkim". -v Requests verbose output. Can be specified multiple times for more and more infor‐ mation. -V Print version number and exit.

CONFIGURATION FILE

The configuration file used by opendkim-spam(1) is expected to be a text file. Empty lines or lines starting with a hash ("#") character are ignored. All other lines should consist of a parameter name followed by one or more whitespace characters, then followed by its intended value. Parameters generally match command line options (specified above), but when present the command line options override the configuration file options. The list of configuration file parameters and their command line equivalents are as follows; see above for descrip‐ tions: Background -f (opposite meaning) DatabaseBackend -b DatabaseName -d DatabaseHost -h DatabasePassword -p DatabasePort -P DatabaseSpamColumn -s DatabaseUser -u ReporterID -r SkipReceived An integer that defines a number of Received fields that should be skipped while searching for the one that was also seen by opendkim(8) so that this command refers to the same Received field. Defaults to 0. StatisticsFile -o

NOTES

It is possible to compile this application without SQL support, in which case only the StatisticsFile setting has any meaning (and, in fact, it is required in that case).
