I entered the lines exactly as you posted. The print MAIL line I entered on the line after my TO: line and the $BCC line I entered in my .cfg after $admin_email. Addresses are correct, and lines look the same as yours but it didn't work for me.

I'm wondering one thing though. With the mass mailer...wouldn't this send one bcc for each email sent, so if you have 100 email recepients, your bcc will get 100 emails.
