I subscribe to Spamcop email service. I recently noticed that I had the setting to not munge my email address with sent reports and I have now changed that setting however, it seems that the damage is done. There are hundreds of messages now being directed to my spamcop email account. Is there a way to change my account/email name on Spamcop or is it possible to open a new account and transfer credits? TIA chang
