I wrote a patch for Robert Jan Scheer's SpamCopReporter script (mirrored locally). You'll probably want to read that website before proceeding here.

The script in its original form works fine for non-member SpamCop Accounts, but doesn't handle those wanting to use their membership accounts for reporting. I'm posting my patch here because RJ seems very busy and hasn't had time to incorporate/test the changes yet. I also hate spam.

The patch is here. I provide no warranty whatsoever for these changes.

In addition to the changes to the script, there are four new .spamcoprc lines that need to exist:

        username = myuname
        # Your SpamCop Username
        password = mypass
        # Your SpamCop Password
        authenticate = 1
        # Provide credentials to SpamCop (requred if you are a paying member)
        baseurl = http://members.spamcop.net/
        # Base location of SpamCop interface you use (with trailing slash)

Note that some of these config lines replace configuration lines in the original script.

That's it. Let me know if you have additional improvements.
