Cita: Curiosamente hotmail y yahoo por ejemplo si reconocen el "from" del correo, pero las cuentas pop3 reconocen el del servidor.
Lo que hay que corregir es:
Cita: custom "From:" header missing
Incluso el ejemplo mismo de la referencia de php, de la función mail:
<?php
/* recipients */
$to = "Mary <
[email protected]>" . ", " ; // note the comma
$to .= "Kelly <
[email protected]>";
/* subject */
$subject = "Birthday Reminders for August";
/* message */
$message = '
<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>
<td>Joe</td><td>3rd</td><td>August</td><td>1970</td>
</tr>
<tr>
<td>Sally</td><td>17th</td><td>August</td><td>1973</td>
</tr>
</table>
</body>
</html>
';
/* To send HTML mail, you can set the Content-type header. */
$headers = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
/* additional headers */
$headers .= "From: Birthday Reminder <
[email protected]>\r\n";
$headers .= "Cc:
[email protected]\r\n";
$headers .= "Bcc:

/* and now mail it */
mail($to, $subject, $message, $headers);
?>
marca el mismo error.
