Description:
------------
OS       Windows XP home Edition, Redhat Linux 5
Server   Apache 2.2.11
PHP      5.2.9-2


I get this:

Warning: mail(): Failed to connect to mailserver at "localhost" port
25,
verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set().

I tried by changing the php.ini and it does not work.

I hope you can help me

Request: This is the third time I am posting this query to PHP Bugs, But
Still I haven't get any Proper Solutions.

Thanks a lot

Reproduce code:
---------------
<?php

$Name = "sam"; //senders name
$email = "am@example.com"; //senders e-mail adress
$recipient = "am1@example.com"; //recipient
$mail_body = "The text for the mail..."; //mail body
$subject = "Subject for reviever"; //subject
$header = "From: ". $Name . " <" . $email . ">\r\n"; //optional
headerfields

if(mail($recipient, $subject, $mail_body, $header)) //mail command :)
echo "mail sent";
else
echo "mail not sent";
?>


Expected result:
----------------
It has to reach to the destination email id 

Actual result:
