cant send out any email

I keep getting the error

warning: mail() [<a href='function.mail'>function.mail</a>]: Failed to connect to mailserver at &quot;localhost&quot; port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()

in my php code

<?php
// the message
$msg = "Testing";

// use wordwrap() if lines are longer than 70 characters
$msg = wordwrap($msg,70);

// send email
mail("someone@example.com","My subject",$msg);
?>

php.ini

You need to have a SMTP server running, which accept your emails, which are send via PHP. You need to point to it in php.ini.

Your Configuration points to localhost. I think, there is no E-Mail Server on localhost running? If so, double check, if it accept E-Mails from localhost (PHP).

Here is how to setup a server:

For IIS:

Note, that it is configured over IIS6 Console, also if you have the latest one. For Some reason, it can't be configured with the >=IIS7 Console, but still works with the old one, which is also installed.

For Linux:

There is also a good E-Mail Class called PHPMailer, which comes in handy, if we are working with SMTP directly on PHP side:

$mail = new PHPMailer;
$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication

$mail->Username = 'user@example.com';                 // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to

$mail->From = 'from@example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('joe@example.net', 'Joe User');     // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
