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.

Same as above but this time looking for "\n\n".

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 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?
