Well, what I have been doing works, but it's a pain-in-the-you-know-what!
--Right click on the spam message, then "view full header"
--Copy the info in the pop-up, click OK
--Click the FORWARD button
--Paste the header info at the top of the message
--Send to SpamCop
Like I said, it's a pain!
Have a happy day!
