In case anyone else needs it, here is my "quick hack" that stops mail
coming from facebook to a local user called cem.duran:
In spamdyke.c:
1) Find the line that starts with
filter_identical_from_to(current_settings,
¤t_settings->current_options-> (etc -- huge line)
2) copy and paste that line right under it, just change the function
name to
filter_facebook(.....)
so it looks like:
filter_identical_from_to(current_settings,
¤t_settings->current_options->filter_action,
¤t_settings->current_opti....
filter_facebook(current_settings,
¤t_settings->current_options->filter_action,
¤t_settings->current_options->filt.....
filter_recipient_graylist(current_sett.....
3) in filter.c, add this function somewhere:
int filter_facebook(struct filter_settings *current_settings, int
*target_action, int *return_action_locked, struct rejection_data
**target_rejection, struct rejection_data *target_rejection_buf, char
*target_message_buf, int size_target_message_buf)
{
int return_value;
char tmp_sender_address[MAX_ADDRESS + 1];
char tmp_recipient_address[MAX_ADDRESS + 1];
int strlen_sender_address;
int strlen_recipient_address;
return_value = FILTER_DECISION_UNDECIDED;
/* Check if the sender and recipient addresses are the same. */
reassemble_address(current_settings->sender_username,
current_settings->sender_domain, NULL, tmp_sender_address, MAX_ADDRESS,
&strlen_sender_address);
reassemble_address(current_settings->recipient_username,
current_settings->recipient_domain, NULL, tmp_recipient_address,
MAX_ADDRESS, &strlen_recipient_address);
if (strstr(current_settings->sender_domain,"facebook") &&
strstr(current_settings->recipient_username,"cem.duran"))
{
*target_action = FILTER_DECISION_TRANSIENT_DO_FILTER;
set_rejection(current_settings, REJECTION_IDENTICAL_FROM_TO,
target_rejection, target_rejection_buf, target_message_buf,
size_target_message_buf, NULL, NULL, NULL, 0);
SPAMDYKE_LOG_VERBOSE(current_settings,
LOG_VERBOSE_FILTER_IDENTICAL_FROM_TO, tmp_sender_address,
tmp_recipient_address);
return_value = FILTER_DECISION_TRANSIENT_DO_FILTER;
}
return(return_value);
}
4) done, make and copy resulting spamdyke to /usr/local/bin (at least
thats where mine is)
5) PS: Since this function is a copy of the same-sender-and-recipient
function, in the logs you'll see DENIED_IDENTICAL_SENDER_RECIPIENT
in the logs. I said it was a quick hack :)
