Betreff: [Dspam-devel] trouble understanding an extract of agent_shared.c on
process_parseto()
829 int process_parseto(AGENT_CTX *ATX, const char *buf) {
830 char *y = NULL;
831 char *x;
832 char *h;
833
834 if (!buf)
835 return EINVAL;
836 h = strstr(buf, "\r\n\r\n");
buf is the "To: " header line and h is a pointer to into buf if buf contains
"\r\n\r\n". If not found then h = NULL.
837 if (!h) h = strstr(buf, "\n\n");
Same as above but this time looking for "\n\n".
838
839 x = strstr(buf, "<spam-");
840 if (!x)
841 x = strstr(buf, " spam-");
842 if (!x)
843 x = strstr(buf, ":spam-");
844 if (!x)
845 x = strstr(buf, "<spam@");
846 if (!x)
847 x = strstr(buf, " spam@");
848 if (!x)
849 x = strstr(buf, ":spam@");
850 if (x > h) x = NULL;
I'm trying to understand what is the h variable for. I always get h=NULL
on lines 836/837, and then x>h is always true, and the email retraining
wasn't working for me. If I comment line 850, it is working as expected,
and the signature of the forwarded email is retrained as spam.
Probably better for your case would be to extend the parsing of the To header
line to be:
836 h = strstr(buf, "\r\n\r\n");
837 if (!h) h = strstr(buf, "\n\n");
838 if (!h) h = strstr(buf, "\r\n");
839 if (!h) h = strstr(buf, "\n");
What I do not yet understand is why is dspam expecting 2 newlines after
the string, and, if it doesn't find them, assumes that the string is no
good.
It seems that buf, in my case comes with the '\n' already stripped. Just
the string "To: email_address" and it's end,'\0'.
What MTA do you have over there? Can you attach a message in raw format (how
the MTA produced it and DSPAM get's it) here so I can inspect the message?
I'm using Mozilla Thunderbird for composing, and delivering on a postfix
server, which then sends the message to dspam via LMTP.
I'm attaching the dspam.messages for that message.
Thanks
