Here's the script that's builds/sends the email:
$boundary = md5(date('U'));
$to = $email;
$subject = "My Subject";
$headers = "From:
[email protected]" . "\r\n".
"X-Mailer: PHP/".phpversion() ."\r\n".
"MIME-Version: 1.0" . "\r\n".
"Content-Type: multipart/alternative; boundary=--$boundary". "\r\n".
"Content-Transfer-Encoding: 7bit". "\r\n";
$text = "You really ought remember the birthdays";
$html = '<html>
<head>
<title>Birthday Reminders for August</title>
</head>
<body>
<p>Here are the birthdays upcoming in August!</p>
<table>
<tr>
<th>Person</th><th>Day</th><th>Month</th><th>Year</th>

<tr>

</tr>
<tr>
<td>Sally</td><td>17th</td><td>August</td><td>1973</td>
</tr>
</table>
</body>
</html>
';
$message = "Multipart Message coming up" . "\r\n\r\n".
"--".$boundary.
"Content-Type: text/plain; charset=\"iso-8859-1\"" .
"Content-Transfer-Encoding: 7bit".
$text.
"--".$boundary.
"Content-Type: text/html; charset=\"iso-8859-1\"".
"Content-Transfer-Encoding: 7bit".
$html.
"--".$boundary."--";
mail("
[email protected]", $subject, $message, $headers);
It sends the message just fine, and my recipient receives it, but they get the whole thing in text/plain instead of in multipart/alternative. Viewing the source of the received message gives this (lots of cruft removed):

It looks like the content-type header is getting changed along the way from multipart/alternative to text/plain. I'm no sysadmin, so if this is a sendmail issue I'm in way over my head. Any suggestions?
