Mit PEARs Mail und Mail_mime sieht das ganze so aus:
PHP-Code:
require_once 'Mail.php';
require_once 'Mail/mime.php';
$mime = &new Mail_mime;
$mime->setHTMLBody($html);
$mime->setTXTBody($txt);
$addh = array(
'From' => 'admin@example.com',
'Subject' => 'Test'
);
$body = $mime->get();
$hdrs = $mime->headers($addh);
$mail = &Mail::factory('mail');
$mail->send($to, $hdrs, $body);
