SpamCop FAQ : Help for abuse-desks and administrators :
How do I get in touch with the person who filed the complaint?
Just reply to it. At one time, SpamCop would anonymize spam
reports, but that has changed. All reports that pass through this server
have verified, valid return addresses. Of course, I can't make the person
read or respond, but your mail should not bounce.
If you feel that SpamCop is being used in an abusive manner,
I want to hear about it. SpamCop can be used to track its own complaints, so you can easily figure out where the complaint originated and ask the users's ISP to take disciplinary action.
