HTML mail

[lucianoes]

    Dear friends,
    I am trying to send HTML mail, but instead of a formatted HTML page I am getting plain text full of HTML code. What am I doing wrong? Here is the code I am using:

<?php
$page = file("http://www.geocities.com/wfbrasil/index.html", "r");
if (!$page)
{print "Ooops! Couldn't find the page!"; die;}
else {$content = join("", $page);}
print $content; //so that I see the result in my browser

$header = "Content-Type: text/html; charset=iso-8859-1;\nContent-Transfer-Encoding: 7bit\nFrom: [e-mail]\nReply-To: [e-mail]\nX-Mailer: PHP mail";
global $content, $header;
mail("[e-mail]", "HTML test", $content, $header);
?>

    Thank you,
