DDccccssiigghhtt reads one or more lines containing DCC checksums, reports them
to a DCC server, and writes a X-DCC header line. It can be used to
report checksums obtained from dccproc(8) using --CC.
The following options are available:
--VV displays the version of the DCC raw checksum interface.
--dd enables debugging output from the DCC client library. Additional --dd
options increase the number of messages.
--QQ only queries the DCC server about the checksums instead of reporting
and then querying. This is useful when ddccccssiigghhtt is used to filter
mail that has already been reported to a DCC server by another DCC
client such as dccm(8). This can also be useful when applying a
private white or black list to mail that has already been reported
to a DCC server. No single mail message should be reported to a DCC
server more than once per recipient, such as would happen if
ddccccssiigghhtt is not given --QQ when processing a stream of mail that has
already been seen by a DCC client. Additional reports of a message
increase its apparent "bulkness."
overrides the default DCC home directory, which is often /var/dcc.
specifies a name or path of the memory mapped parameter file instead
of the default _m_a_p in the DCC home directory. It should be created
with the cdcc(8) command.
specifies an optional file containing SMTP client IP addresses and
SMTP headers of mail that do not need X-DCC headers and whose check-
sums should not be reported to the DCC server. It can also contain
checksums of spam. If the pathname is not absolute, it is relative
to the DCC home directory. Thus, individual users with private
whitelists usually specify them with absolute paths. It is useful
to _i_n_c_l_u_d_e a common or system-wide whitelist in private lists.
The format of the ddccccssiigghhtt whiteclnt file is the same as the
_w_h_i_t_e_l_i_s_t file required by dbclean(8) and dccsight(8). Because this
list is used frequently, a companion file is used. It has the same
pathname but with an added suffix of _._d_c_c_w. After being created
empty, it will contain an automatic memory mapped hash table of the
specifies the number of addressees of the message if other than 1.
The string _m_a_n_y instead of a number asserts that there were too many
addressees and that the message is unsolicited bulk email.
specifies an input file instead of standard input. If not absolute,
the pathname is interpreted relative to the directory in which
ddccccssiigghhtt was started.
specifies how messages should be logged. _L_t_y_p_e must be _e_r_r_o_r or
_i_n_f_o to indicate which of the two types of messages are being con-
trolled. _L_e_v_e_l 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, _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, _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 through _L_O_C_A_L_7. The default is equivalent to
--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
