apache + php4 + mail() + sendmail

["Sylvain Blanc - CRI du Pays De Gex et du Bassin Bellegardien" <sblanc@cri01.org>]

hello,

When i use mail() function in php4 and i write a wrong "to:" email,
the error notification is send to the apache user (www-data) instead of me

after investigation, i find the problem: i can't change the header like i
want

    $headers .= "Return-Path: <toto@8-D.org>\r\n";
    $headers .= "From: toto <toto@8-D.org>\r\n";
    $headers .= "X-Sender: <toto@8-D.org>\r\n";
    $headers .= "X-Mailer: PHP/". phpversion() ."\r\n";
    $headers .= "X-Priority: 3\r\n"; //  Message urgent!
    $headers .= "Errors-To: <toto@8-D.org>\r\n";
    $headers .= "Content-Type: text/html; charset=iso-8859-1\r\n";

My Return-Path is not use

What is the solution ?
Must i make a new sendmail rule ?
