11 DDccccssiigghhtt reads one or more lines containing DCC checksums, reports them
12 to a DCC server, and writes a X-DCC header line. It can be used to
13 report checksums obtained from dccproc(8) using --CC.
14
15 OOPPTTIIOONNSS
16 The following options are available:
17
18 --VV displays the version of the DCC raw checksum interface.
19
20 --dd enables debugging output from the DCC client software. Additional
21 --dd options increase the number of messages.
22
23 --QQ only queries the DCC server about the checksums instead of reporting
24 and then querying. This is useful when ddccccssiigghhtt is used to filter
25 mail that has already been reported to a DCC server by another DCC
26 client such as dccm(8). This can also be useful when applying a
27 private white or black list to mail that has already been reported
28 to a DCC server. No single mail message should be reported to a DCC
29 server more than once per recipient, such as would happen if
30 ddccccssiigghhtt is not given --QQ when processing a stream of mail that has
31 already been seen by a DCC client. Additional reports of a message
32 increase its apparent "bulkness."
33
34 --CC outputs the checksums for the message as well as the X-DCC header.
35
36 --hh _h_o_m_e_d_i_r
37 overrides the default DCC home directory, _/_v_a_r_/_d_c_c.
38
39 --mm _m_a_p
40 specifies a name or path of the memory mapped parameter file instead
41 of the default _m_a_p in the DCC home directory. It should be created
42 with the cdcc(8) command.
43
44 --ww _w_h_i_t_e_c_l_n_t
45 specifies an optional file containing SMTP client IP addresses and
46 SMTP headers of mail that do not need X-DCC headers and whose check-
47 sums should not be reported to the DCC server. It can also contain
48 checksums of spam. If the pathname is not absolute, it is relative
49 to the DCC home directory. Thus, individual users with private
50 whitelists usually specify them with absolute paths. It is useful
51 to _i_n_c_l_u_d_e a common or system-wide whitelist in private lists.
52
53 The format of the ddccccssiigghhtt whiteclnt file is the same as the
54 _w_h_i_t_e_l_i_s_t file required by dbclean(8) and dccsight(8). Because this
55 list is used frequently, a companion file is used. It has the same
56 pathname but with an added suffix of _._d_c_c_w. After being created
57 empty, it will contain an automatic memory mapped hash table of the
58 main file.
59
60 --tt _t_a_r_g_e_t_s
61 specifies the number of addressees of the message if other than 1.
62 The string _m_a_n_y instead of a number asserts that there were too many
63 addressees and that the message is unsolicited bulk email.
64
65 --ii _i_n_f_i_l_e
66 specifies an input file instead of standard input. If not absolute,
67 the pathname is interpreted relative to the directory in which
68 ddccccssiigghhtt was started.
69
70 --LL _l_t_y_p_e_,_f_a_c_i_l_i_t_y_._l_e_v_e_l
71 specifies how messages should be logged. _L_t_y_p_e must be _e_r_r_o_r, _i_n_f_o,
72 or _o_f_f to indicate which of the two types of messages are being con-
73 trolled or to turn off all syslog(3) messages from ddccccssiigghhtt. _L_e_v_e_l
74 must be a syslog(3) level among _E_M_E_R_G, _A_L_E_R_T, _C_R_I_T, _E_R_R, _W_A_R_N_I_N_G,
75 _N_O_T_I_C_E, _I_N_F_O, and _D_E_B_U_G. _F_a_c_i_l_i_t_y must be among _A_U_T_H, _A_U_T_H_P_R_I_V,
76 _C_R_O_N, _D_A_E_M_O_N, _F_T_P, _K_E_R_N, _L_P_R, _M_A_I_L, _N_E_W_S, _U_S_E_R, _U_U_C_P, and _L_O_C_A_L_0
77 through _L_O_C_A_L_7. The default is equivalent to
78 --LL _i_n_f_o_,_M_A_I_L_._N_O_T_I_C_E --LL _e_r_r_o_r_,_M_A_I_L_._E_R_R
