It takes about two lines of code to record the contents of $BLOCK2 in a X-Spam-header for later filtering.
How would I do this... do you have a code snippet as an example
You still can assign 'non-false-positives-lists' like SBL, UPL, SORBS and alike to $BLOCK and reject them right away.
I have setup some of the DNS based filters to set the $BLOCK2 variable. I'm assuming I'll have to get maildrop to check this and then file the mail away in a spambox, but AFAIK maildrop can't access the BLOCK or BLOCK2 variables (running in delivery mode)
Inserting a header is the only way to communicate with the delivery-module. I am also planning a patch there so maildrop wont be needed anymore for quarantine to the Spamfolder.
At courier/submit.C, linenumbers are probably somewhat off due to other stuff, but copy&paste should work. One probably should sanitize the contents, non-ascii could mess up everything.
char *safe = rfc2047_encode_str(header, RFC2045CHARSET);
which works as epected, or maybe even script-alike:
header += rfc2047_encode_str(p, RFC2045CHARSET);
but I dont include that here until tested, and dont really know what would happen with embedded \n. Improved and tested patch welcome ;)
