Mail::SpamAssassin::PlUser:Contributed PerMail::SpamAssassin::Plugin::DCC(3pm)



NAME
       Mail::SpamAssassin::Plugin::DCC - perform DCC check of messages

SYNOPSIS
         loadplugin     Mail::SpamAssassin::Plugin::DCC

DESCRIPTION
       The DCC or Distributed Checksum Clearinghouse is a system of servers
       collecting and counting checksums of millions of mail messages. The
       counts can be used by SpamAssassin to detect and reject or filter spam.

       Because simplistic checksums of spam can be easily defeated, the main
       DCC checksums are fuzzy and ignore aspects of messages.  The fuzzy
       checksums are changed as spam evolves.

       Note that DCC is disabled by default in "init.pre" because it is not
       open source.  See the DCC license for more details.

       See http://www.rhyolite.com/anti-spam/dcc/ for more information about
       DCC.

USER OPTIONS
       use_dcc (0|1)       (default: 1)
           Whether to use DCC, if it is available.

       dcc_body_max NUMBER
       dcc_fuz1_max NUMBER
       dcc_fuz2_max NUMBER
           This option sets how often a message's body/fuz1/fuz2 checksum must
           have been reported to the DCC server before SpamAssassin will
           consider the DCC check as matched.

           As nearly all DCC clients are auto-reporting these checksums, you
           should set this to a relatively high value, e.g. 999999 (this is
           DCC's MANY count).

           The default is 999999 for all these options.

ADMINISTRATOR OPTIONS
       dcc_timeout n       (default: 8)
           How many seconds you wait for DCC to complete, before scanning
           continues without the DCC results.

       dcc_home STRING
           This option tells SpamAssassin specifically where to find the dcc
           homedir.  If "dcc_path" is not specified, it will default to
           looking in "dcc_home/bin" for dcc client instead of relying on
           SpamAssassin to find it in the current PATH.  If it isn't found
           there, it will look in the current PATH. If a "dccifd" socket is
           found in "dcc_home", it will use that interface that instead of
           "dccproc".

       dcc_dccifd_path STRING
           This option tells SpamAssassin specifically where to find the
           dccifd socket.  If "dcc_dccifd_path" is not specified, it will
           default to looking in "dcc_home" If a "dccifd" socket is found, it
           will use it instead of "dccproc".

       dcc_path STRING
           This option tells SpamAssassin specifically where to find the
           "dccproc" client instead of relying on SpamAssassin to find it in
           the current PATH.  Note that if taint mode is enabled in the Perl
           interpreter, you should use this, as the current PATH will have
           been cleared.

       dcc_options options
           Specify additional options to the dccproc(8) command. Please note
           that only characters in the range [0-9A-Za-z ,._/-] are allowed for
           security reasons.

           The default is "undef".

       dccifd_options options
           Specify additional options to send to the dccifd(8) daemon. Please
           note that only characters in the range [0-9A-Za-z ,._/-] are
           allowed for security reasons.

           The default is "undef".
