Yes. Using \"CC\" in the 4th slot for extra headers causes a header with someone\'s address to appear on the mail, but the mail doesn\'t actually get CC\'ed to them.
I\'ll try the bcc, but I\'m not expecting it to work.
What\'s lame is that the PHP Manual entry on mail() states pretty clearly that you can submit a list of recipients seperated by commas and it will send to all listed. But this doesn\'t work, at least, not on everyone\'s system. There are posts all over about it. Just do a search on \"php4 mail multiple recipients\" on this search or Google. Nobody can seem to figure out why it doesn\'t work.
