Mail problem !

Hello ! I use PHP4.03pl1 on a Linux System that use Postifix. But it have sendmail too in /usr/sbin I would like PHP uses sendmail for sending mails. In php.ini, that's ok. The mail program is /usr/sbin/sendmail -t -i ( I checked that whith phpinfo() ) But when I use the mail function, php keeps using Postfix.... It will be ok if I didn't have a problem I think due to Postifx (that s why I want to use Sendmail ). In my srcipt I do : .... $bcc="From: me@domain.com\r\nbcc: ".$bcc; mail("you@domain.com",$SUBJECT,$MESSAGE,$bcc); ... And I receive this message : To: you@domain.com Subject: subject.... bcc: joey@worldnet.fr,a.girou@... etc... My message... The problem is that Bcc field appears in the message and the mail is only sent to "you@domain.com" so, How can I force PHP to use sendmail, or does anyone have an idea about my problem on header fields with Postfix ??
