mail not sent when headers are used

[vjayis]

hi
i m using mail() function to send mails and it works well for an sample message without including headers.,

when i include headers and send an html content or an sample content i didnt receive an mails ., no mails in spam folder too..

here is my code:

<?php
$fname='vijay';
$header="MIME-Version: 1.0\r\n"; 
$header.="Content-type: text/plain; charset=iso-8859-1\r\n"; 
$header.="From: ".$fname." <from@example.com>\r\n";

$msg='
<table width="100%" cellspacing="0" cellpadding="0">
  <tr>
    <th align="right" valign="top" scope="row">Name</th>
    <th align="left" valign="top" scope="row">&nbsp;</th>
    <th align="left" valign="top" scope="row">Vijay</th>
  </tr>
  <tr>
    <th align="right" valign="top" scope="row">Address</th>
    <th align="left" valign="top" scope="row">&nbsp;</th>
    <th align="left" valign="top" scope="row">Madurai</th>
  </tr>
  <tr>
    <th align="right" valign="top" scope="row">Tel</th>
    <th align="left" valign="top" scope="row">&nbsp;</th>
    <th align="left" valign="top" scope="row">9876543210</th>
  </tr>
</table>
';

$subject="testing".date('d-M-Y H:i:s');
$to='to@example.com';

mail($to,$subject,$msg,$header);

echo "success";
?>

i got the message "success" printed but no mails received.

thanks

you always get printed "success", even if the mail() function fails. you have to explicitly test the function’s return value to make sure.

tried using

<?php
$return=mail($to,$subject,$msg,$header);
echo "success";
var_dump($return);
echo $return;

?>

and got result as

successbool(fal se)

so what do i want to do..
