Mail::SpamAssassin::Plugin::DCC(3)   User Contributed Perl Documentation  Mail::SpamAssassin::Plugin::DCC(3)



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".
