How to get mail() email to Yahoo account

[mag0103]

Hello everyone:

 

I am trying to send a very simple email.  I've tried everything in the header, still the mail() function doesn't email to my yahoo as well as my work email.  Please find the code below and tell me what i am doing wrong here:

 

    $userid = $_SESSION['username'];

    $email_from = "[email protected]";

    $to =  $_POST['email'];

    $subject = $_POST['subject'];

    $note = $_POST['note'];

 

if($to && $subject && $note) {

    $body = $userid ." has invited you to a meeting for ". $subject ."\n\n". "NOTE: " . $note;

 

$headers = "From: " . $email_from . "\r\n";

$headers .= "To: " . $to . "\r\n";

$headers .= "Reply-To: ". $email_from . "\r\n";

$headers .= "X-Mailer: PHP / " . phpversion();

 

if(mail($to, $subject, $body, $headers)) {

  echo "mail sent";

  echo "<script type='text/JavaScript'>

          setTimeout('window.close()',500);

        </script>";

}

else {

  print "mail not sent, please try later.";

}

     

} // end check if primary fields are filled

 

else {

?>

 

<style TYPE="text/css">

form {

  font-family:arial;

  font-size:12px;

  font-weight:bold;

}

label { display:block;float:left;width:100px;clear:left; }

.clear { clear:both; }

 

</style>

 

<form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>" name="form">

<label for="from">From:</label>

<b><?php echo $userid; ?></b>

<div class="clear"></div>

<label for="email">*To:</label>

    <input type="textbox" name="email" value="">

<div class="clear"></div>

<label for="subject">*Subject:</label>

    <input type="textbox" name="subject" value="">

<div class="clear"></div>

<label for="note">*Note: </label>

    <textarea name="note"></textarea>

<div class="clear"></div>

<label> </label>

<input type="submit" name="btn_sendemail" value="Send!" class="btn" />

<div class="clear"></div>

<label><b><i>* required fields</i></b></label>

</form>

 

I am so desperate.  Please help.  Thank you much.
