NAME

6       Mail::SpamAssassin::Plugin::DCC - perform DCC check of messages
7

SYNOPSIS

9         loadplugin     Mail::SpamAssassin::Plugin::DCC
10

DESCRIPTION

12       The DCC or Distributed Checksum Clearinghouse is a system of servers
13       collecting and counting checksums of millions of mail messages. The
14       counts can be used by SpamAssassin to detect and reject or filter spam.
15
16       Because simplistic checksums of spam can be easily defeated, the main
17       DCC checksums are fuzzy and ignore aspects of messages.  The fuzzy
18       checksums are changed as spam evolves.
19
20       Note that DCC is disabled by default in "init.pre" because it is not
21       open source.  See the DCC license for more details.
22
23       See http://www.rhyolite.com/anti-spam/dcc/ for more information about
24       DCC.

USER OPTIONS

27       use_dcc (0⎪1)       (default: 1)
28           Whether to use DCC, if it is available.
29
30       dcc_body_max NUMBER
31       dcc_fuz1_max NUMBER
32       dcc_fuz2_max NUMBER
33           This option sets how often a message's body/fuz1/fuz2 checksum must
34           have been reported to the DCC server before SpamAssassin will con‐
35           sider the DCC check as matched.
36
37           As nearly all DCC clients are auto-reporting these checksums, you
38           should set this to a relatively high value, e.g. 999999 (this is
39           DCC's MANY count).
40
41           The default is 999999 for all these options.
42

ADMINISTRATOR OPTIONS

44       dcc_timeout n       (default: 8)
45           How many seconds you wait for DCC to complete, before scanning con‐
46           tinues without the DCC results.
47
48       dcc_home STRING
49           This option tells SpamAssassin specifically where to find the dcc
50           homedir.  If "dcc_path" is not specified, it will default to look‐
51           ing in "dcc_home/bin" for dcc client instead of relying on SpamAs‐
52           sassin to find it in the current PATH.  If it isn't found there, it
53           will look in the current PATH. If a "dccifd" socket is found in
54           "dcc_home", it will use that interface that instead of "dccproc".
55
56       dcc_dccifd_path STRING
57           This option tells SpamAssassin specifically where to find the
58           dccifd socket.  If "dcc_dccifd_path" is not specified, it will
59           default to looking in "dcc_home" If a "dccifd" socket is found, it
60           will use it instead of "dccproc".
61
62       dcc_path STRING
63           This option tells SpamAssassin specifically where to find the
64           "dccproc" client instead of relying on SpamAssassin to find it in
65           the current PATH.  Note that if taint mode is enabled in the Perl
66           interpreter, you should use this, as the current PATH will have
67           been cleared.
68
69       dcc_options options
70           Specify additional options to the dccproc(8) command. Please note
71           that only characters in the range [0-9A-Za-z ,._/-] are allowed for
72           security reasons.
73
74           The default is "undef".
75
76       dccifd_options options
77           Specify additional options to send to the dccifd(8) daemon. Please
78           note that only characters in the range [0-9A-Za-z ,._/-] are
79           allowed for security reasons.
80
81           The default is "undef".
