I've found some scripts in the scripts section but when I use it to report SPAM SpamCop gives an error :
Parsing text part
error: couldn't parse head
Message body parser requires full, accurate copy of message
and provides a link to more information.
The script seems to be a few years old so I guess it's no longer updated or maintained ?
I also found a DNSBL script on these forums but that's also from 2004 and the needed files are no longer available.
I use RBL myself for my forums and they work pretty good so if there is a script that can use these blacklists to filter emails that would be great (even better would be an option to submit spammers to that blacklist so others benefit from it, I guess that's also something SpamCop.net does since the BNSBL script also checked there for spam).
